EPC is Proud to Announce "Superseal"; The Encoder Designed to Handle Your Worst Nightmare

Using optical shaft encoders in nasty environments - caustic, fine dust, saline, and the like - has always been, at best, a chancy proposition. The electronics and other critical components at the heart of an optical encoder do not lend themselves to being used in these types of difficult environments. At least that used to be the case, but Superseal, the encoder designed by Encoder Products Company (EPC) specifically for your worst nightmare, goes a long way towards solving that problem.

Built on the time tested and ultra reliable Model 725 Size 25 Optical Shaft Encoder platform, Superseal starts by adding double o-rings to the case seal and two Teflon seals to the bearing assembly, but it doesn't stop there. A double case, sealed encoder within a sealed encoder design, means that, even if the nasty stuff gets past the first layer of protection, extra layers still won't let it reach the critical components. Add to that still more sealing around the cable ports, and special connector options, including the Turck Eurofast, and you have an encoder that can "take a lickin' and keep on tickin'". Superseal was beta tested in some of the worst environments imaginable, like battery manufacturing plants, off shore oil rigs, etc., and while we can't say it always survived, it always stayed operational at least three to five times longer than any alternative. Superseal is definitely worth a try in your next "worst nightmare".

Superseal, like all Accu-Coder brand encoders, is manufactured to EPC's exacting standards to ensure the quality you've come to expect from the Accu-Coder brand. And, with EPC's exclusive three-year warranty, you can be confident your Accu-Coder will provide years of trouble free use.

The Best Things in Life Come in Small Packages!

Encoder Products Company is pleased to introduce the New Model 15 Line of Encoders. Designed with the OEM in mind, the Model 15 Line provides big benefits in a small package. The Model 15 is available in three styles: Shaft (S), Thru-bore (T), and Hollow bore (H). These small units have a low 1" profile in an industry standard size 15 (1.5"diameter) housing. But don't let the small size fool you, The Model 15 Line provides unequalled accuracy, high-speed performance, and up to 12-pole commutation. Each style features a lightweight Zytel housing, and precision bearings, which can be sealed up to a rating of IP64. Ideal for brushless servo-mount motor applications, the Model 15 can also withstand the harsh environments of a variety of industrial applications. The Model 15 also features an optional 100°C temperature capability, allowing servo-motors to operate at high speed outputs, perfect for specialized assembly machinery or robotics applications. However, the MAIN advantage of the Model 15 Line is it's economical PRICE!

Models 15T and 15H will easily mount over shaft sizes up to 10mm or 0.375", and feature EPC's innovative anti-backlash mounting system, making these units extremely easy to install, and much more tolerant to axial misalignment or radial shaft run-out. Model 15S is designed for those applications that require a shaft encoder, and features a variety of mounting options.

Every AccuCoder brand encoder is manufactured to EPC's exacting standards, and features EPC's exclusive 3-year standard product warranty, ensuring you years of trouble free use. With the miniscule package and price on the Model 15 encoder, it is easy to say, "No other encoder can give you this much bang for the buck!" To get this many important benefits, from such a small, economical encoder, you can clearly see that "The BEST things in life come in small packages!"

Bi-Directional Encoder Offers Resolutions from 1 to 10,000.

Encoder Products Company (EPC), manufacturer of the popular Accu-Coder brand of encoders, has made one of the most versatile members of its Accu-Coder Cube Series, the Model 715, even more flexible by dramatically extending its range of available resolutions. Simply put, this means that you can now order a Model 715 in nearly any resolution from 1 to 10,000!

 The Model 715 Bi-directional Encoder is a very flexible member of the Cube Series Accu-Coder that operates in one of two modes. In the first mode (Model 715-1), it provides a constant pulse width output on one output channel for clockwise shaft rotation, and on another channel for counterclockwise rotation. In the second mode (Model 715-2), the constant pulse width output is on one channel regardless of the direction of shaft rotation. Another channel is a direction line indicator that outputs a logic level "1" for clockwise shaft rotation, and a logic level "0" for counterclockwise rotation. Making the Model 715 even more versatile is the fact that the pulse width itself is programmable from 10 microseconds to 100 milliseconds. In addition, the Model 715 can be ordered with shaft sizes from 0.250" to 0.625".

 The Model 755A is manufactured to EPC's exacting standards to ensure the quality you've come to expect from the Accu-Coder brand. And with EPC's exclusive three-year warranty, you can be confident your Accu-Coder will provide years of trouble free use.

Less is More: Reduced Number of Variants, Smaller Size.

Lenze has developed a decentralised drive solution that is specially tailored to the requirements of horizontal materials handling systems. Coming from Lenze as a specialist in Motion Centric Automation, this mechatronic solution combines the well-known Lenze Smart Motor with the g500 gearbox series. The efficiency of the Lenze Smart Motor plus gearbox is more than 94 per cent over the entire ratio range. This enhances the energy efficiency of the machine in question as a whole. With a single version of this motor-gearbox combination, variable motor speeds with a constant torque are possible. This renders superfluous many of the different variants of such combinations that are normally needed today. What's more, the motor's speed of rotation can be adjusted with the help of a smartphone and NFC technology.

In the area of horizontal materials handling, many drive concepts now in use rely on complex frequency inverters in order to achieve a high starting torque. In contrast, the continuous torque is usually relatively low. As a result, the drives are over-dimensioned and consume far too much energy. Lenze has taken a very close look at such applications and questioned the conventional solutions usually applied in these cases. The result of this approach, which is aimed at improving the concrete application, is a smart drive package that performs its respective materials-handling tasks very precisely and effectively. This is made possible by the intelligent interaction of the components.

The Lenze Smart Motor combines the simplicity of a mains-operated motor with the advantages of an electronic drive control unit, whereby the electronics and the software are integrated in the drive and, together with the mechanics, form a single aggregate unit. Due to the freely adjustable speed, the variety of different drives in use can be reduced by up to 70 per cent as only one geared-motor version is sufficient for all tasks. Time-consuming and costly version management is thus no longer necessary, as a result of which the number of drives that the mechanical engineering company has to keep in stock can be reduced and costs can be lowered sustainably. Moreover, the operator can control the equipment with a smartphone and the use of "near field communication". The advantage of all this is that the motor's speed can be converted into torque intelligently and precisely. Due to intelligence in the terminal box, the Lenze Smart Motor can flexibly cover speeds of between 500 to 2600 revolutions per minute at constant torque. Mechanical engineering companies and plant operators can therefore profit from this carefully designed drive package in several different ways: a highly modern operator control concept, low energy consumption and thus reduced operating costs and fewer different drives with different ratings.

Electromagnetic Braking Systems in Wind Turbines

INTORQ brakes have been in use for many years in wind power installations and special requirements of this field of application are high reliability, long maintenance cycles, resistance to environmental influences and a tight braking-torque tolerance.

For pitch drives, we have developed stored-spring brakes as holding brakes that have to display a specific mode of emergency manner even after a failure. The brake casing is encapsulated or suitable for tachometer mounting.

In azimuth drives, brakes from our modular BFK458 series are used. They keep the turbine aligned in the wind. In the event of a fault, the brakes have to act as a friction clutch to enable the gondola to move with the wind.

In the offshore area, the requirements for corrosion protection and robustness are very high. Encapsulated version with special surface protection are used here.

Leuze Extremely Tough 328 Series Sensors

Leuze electronic is releasing new cylindrical sensors for particularly difficult conditions.

The new 328 series is based on the optical platform of the well-known stan-dard 318B series and, thanks to the metal sleeve in the housing, offers hig-her mechanical strength than the standard product made of high-quality plastic. The operating principles available in the new series, which range from throughbeam photoelectric sensors to retro-reflective photoelectric sensors to light scanners with sensitivity adjustment via teach button, combine all relevant designs with cable or plug connection. An adjustable retro-reflective photoelectric sensor model with polarization filter for particularly tricky applications is also included in the product line.

With ranges of up to 15 m (throughbeam photoelectric sensors), 6 m (retro-reflective photoelectric sensors) and 1 m (light scanners), they fit perfectly in a variety of applications for object detection in materials handling and packaging technology. The cylindrical sensor is very well-received; these sensors are especially popular for integration into constricted environments and into assemblies in transport systems or other machines. In many pro-duction processes and internal transport systems, these optical sensors are used for the detection of objects and thereby control processes or partial steps. The highly-visible light spot facilitates alignment and two antivalent outputs expand the application options.

New Leuze Sensor Series 18B

With the 18B sensor series, Leuze electronic expands its extensive line of sensors in the area of high-performance sensors for transparent media.

Compared to its predecessor – the 18 series – the new sensor scores with a more robust housing, smaller dimensions, shorter response time, higher switching frequency, improved adjustability of the switching point and a tracking function for extending the cleaning interval (50x). Due to the new features, it is possible to reliably detect fast, small, thin and transparent objects, such as foils, even under extreme environmental conditions – a true plus, for example, in the beverage industry.

The visibility of the light spot and the LED display have also been improved, thereby simplifying start-up and operation. The optics minimize light beam tolerances to the extent that mounting can be quickly performed without alignment. The electrical connection is established either via the M12 plug or the integrated cable.

Flomotion Pumps Hard-to-Handle Chemicals with the SMV

Flomotion Systems develops and manufactures unique seal-less peristaltic pumps that eliminate loss-of-prime failures in chemical feed applications. Typical markets served include water & wastewater treatment, chemical, food & dairy, pharmaceutical, pulp & paper, energy management, power and irrigation.

A long-time user of the Lenze drives, Flomotion incorporated the economical, compact and lightweight SMVector in the design of their 2001HEC Series pumps. The Flomotion 2001HEC Series are rugged, reliable and cost effective industrial hose pumps built to succeed in harsh industrial environments. Several features of the SMVector make it a perfect fit for the job, including a removable terminal cover, easy access for control and power wiring and the fact that it can handle a wide range of operating temperatures from -10 to 55ÂșC. Last but not least, according to Flomotion, the SMVector offers better protection against electrical shock than any other NEMA 1 controller on the market.

Mounting the SMVector controller directly to the pump allows Flomotion to optimize precious panel space and offer its customers outstanding convenience. The unique Electronic Programmable Module (EPM) stores the drive’s parameter configuration, greatly simplifying initial setup.

Centrifugal and pumping applications, especially those moving fluids or a mixture of wet and dry ingredients, present a challenge because the speed is affected by the load. Fluid moving applications require "variable speed" - a drive and motor that can produce the necessary horsepower to move the load at a constant speed. The motor will draw from the drive the amount of current it needs to 'do the job'. The SMVector drive works well in this type of application because the speed can be controlled tightly in vector mode (more torque/less speed) or loosely in V/Hz mode to determine just the right amount of speed.

The development of Ultra-compact (2520-size) Voltage Controlled Crystal Oscillator

NIHON DEMPA KOGYO CO., LTD. has developed an ultra-compact Voltage-Controlled Crystal Oscillator NV2520SA.

With the spread of digital broadcasting-capable mobile devices, there is a growing need for a compact and high-performance VCXO as a clock oscillator for the processing of complex image signals.

In order to meet this need, with the use of the high density mounting technology, we have developed NV2520SA , which is one of the industry’s smallest package (Dimension: 2.5 × 2.0 × 0.8mm). Although it is ultra-compact, it has Frequency control range "Min. ±100×10-6". Also, it has a wide Operating temperature range of from - 40 °C to +85 °C, and can be used under a wide variety of environmental conditions.

The development of an Enable/Disable(*) function-equipped TCXO for GPS applications

NIHON DEMPA KOGYO CO., LTD. has developed an ultra-compact Temperature Compensated Crystal Oscillator NT2016SB.

Recently, there has been a growing need for GPS-equipped mobile phones and mobile terminals. Amid the need for miniaturization, an extremely high precision has been required for the GPS function on these devices, and the need to reduce the power consumption has increased due to the multifunctionality of mobile phones.

In order to meet these needs, we have developed an ultra-compact, light and low profile (0.8 mm max) TCXO NT2016SB which has highly stable frequency-temperature characteristics and operates with lower power consumption due to the Enable/Disable function.

The development of the world's first* ultralow power-driven (0.8V min) crystal clock oscillator

NIHON DEMPA KOGYO CO., LTD. has developed the world's first environment-friendly, miniaturized (2.5 x 2.0 x 0.9 mm) and ultralow power-driven crystal clock oscillator “NZ2520SF”.

Recently, eco-friendly products have become popular in various applications, and the move towards energy conservation has accelerated. For this reason, there is a strong demand for electronic components constituting these products to be environment-friendly, and due to the requirements for long-life battery and multi-functionality, energy conservation through both miniaturization and power saving is desired especially in compact devices such as mobile phones or handheld devices. In order to meet these market needs, we have developed a crystal clock oscillator that can be operated at ultralow power (0.8V min).

“NZ2520SF” is the world's first* 2.5 x 2.0 mm type crystal clock oscillator that can be operated at ultralow power (0.8V min). In comparison with existing crystal clock oscillators, the operating voltage is about 50% lower and the current consumption is at least 40% lower (Fig.1). This is equivalent to approximately 70% reduction in power consumption.

This product helps achieve low-power operation, has significant increase in battery life and reduction in environmental load especially in mobile devices such as multi-functional mobile phones, silicon audio players, PND (Personal Navigation Device)and notebook computers. Due to its wide frequency range (1.5 to 50MHz), other than mobile application devices, it can be used in a wide range of electronic devices, leading to environmental load reductions in various fields in the electronics industry.

NDK Develops VCXO with Low Phase Jitter Improving Signal Quality of Optical Communication Networks

NIHON DEMPA KOGYO CO., LTD. (President : Hiroshi Takeuchi) has developed and started to ship mass-produced compact high frequency range type VCXO (Voltage-Controlled Crystal Oscillators).

Miniaturization of devices is required at high-speed wireless broadband networks and base stations for mobile communications from the perspective of establishing low-cost installations and operation. High frequency clock signals between 600 MHz to 700 MHz are required for the optical transmission devices and optical multiple-wavelength transmission devices used in these base stations and core networks.

In order to meet the market requirements, NDK has developed the “NV7050SA” VCXO. It handles high frequency and has a small package, 7.0 × 5.0mm (one-tenth volume compared to the conventional products) while maintaining the same frequency stability and pull-ability range as the conventional products. Furthermore, ultralow phase jitter is achieved at a few tens of femtoseconds, which is an order of magnitude lower than previously developed products.

PLL frequency multiplication is generally used to obtain high frequencies in the range of hundreds of MHz, however the drawback is phase jitter is magnified during this process which can significantly degrade the quality of transmission signals. Through NDK's proprietary technical knowledge, high frequency fundamental crystal units were designed and applied to obtain high frequencies without the need for PLL frequency multiplication processing. This has enabled the phase jitter to reduce to values of one quarter to one fifth the level of phase jitter produced by conventional PLL multiplication type VCXO.
