Photonic Offers Variable-Focus Laser Diode Modules

Photonic Products is launching a range of variable-focus industrial laser diode modules. Constructed to withstand harsh conditions and satisfy challenging industrial applications, Photonic's new range of variable-focus industrial laser diode modules offers the high performance and the high boresight accuracy of less than 0.25 degrees of the existing range of standard industrial laser modules with the added bonus of user-adjustable focus for greater flexibility and fine tuning.

The range is designed to be a complete original-equipment-manufacturer (OEM) laser solution for heavy-duty manufacturing processes such as micro-machining, marking, cutting, drilling, welding, forming and soldering, along with other industrial laser uses where quality, durability and robust performance are critical. The industrial modules are encapsulated in a hard-coat-anodised case with a scratch-resistant sapphire window to protect the lens.

They are designed and built for ease of use; any time the laser needs to be changed, the connectors - either 2.5mm DC jack or industrial screw-on - make installation and replacement easy and their compact size allows for efficient integration into existing production systems. The variable-focus industrial laser module is available in a variety of wavelengths from 635nm to 830nm with optical output powers from 0.97mW to 27.50mW, with either a standard elliptical output beam or line-generating optics that provide a 45-, 60- or 90-degree full fan angle line, offering straight-line precision without bowing.

The beam is aligned to less than 0.25 degrees to the mechanical axis of the laser, giving high boresight accuracy. With optical output powers from 0.95mW to 27.50mW, an operating voltage of 5VDC regulated +/-10 per cent and an operating temperature from -10C to +50C, the modules are static, surge and reverse polarity protected and RoHS compliant. The standard lens may be replaced by other optical systems such as line or cross generators.

Han® HC 250 high current contact

A Powerful Solution HARTING has developed the new Han® HC 250high current connector as a powerful interface that impresses by requiring little space, transmitting high current intensities and allowing flexible configuration of the number of poles. The HC 250 one-pole crimp module can be connected in various frame geometries to produce the required number of poles in a compact space – and in the existing Han® HPR housing. Technical details: - Rated current 250 A at a rated voltage of 2000 V - Termination cross-sections are: 35 mm2, 50 mm2 and 70 mm2 - Maximum four-pole interfaces in a size 24 B HPR housing, making it particularly suitable for motor connections - High quality plastic with good smoke and inflammability levels - Removal tool for simple installation and removal of the contacts and inserts - Confusion of a number of interfaces is reliably prevented by multiple coding options for the individual inserts The requirements in the railway industry are changing, as

EGCS-D0 Accelerometer Now Available in 10,000g Range

Measurement Specialties, Inc. (NASDAQ: MEAS) has recently redesigned the EGCS-D0 accelerometer to enable it to accurately and reliably measure up to ±10,000g. This rugged device is critically damped, which is the ideal mechanism to protect the accelerometer against ±20,000g impacts and prevent sensor ringing. The EGCS-D0 accelerometer is now available in ranges from ±5g to ±10,000g which makes it ideal for both critical low-g measurements and high-g impacts. These units feature a Wheatstone Bridge mV output with a standard compensated temperature range of 20ºC to 80ºC (other options available). The EGCS-D0 was specifically designed for impact and shock testing in auto safety, aerospace, military and civil engineering applications. Designed to be bolt-mounted, this device operates from 2-15Vdc excitation with electrical output ratiometric to voltage input. Optional triaxial mounting blocks (MTG-F4), signal conditioners (Model 101) and auto-zero inline amplifiers (Model 140) are avai

Ilix Cermet Reamers Are Ideal For Dry Machining Engineers Cutting Tools, the UK agent for Ilix, has introduced Ilix solid-carbide and cermet reamers for the machining of hard metals. The machine reamers 6372C and 6323 allow the production of high-precision holes with good surface finish. Compared with HSS, the solid-carbide qualities enable the increase of cutting parameters and tool life. The quality of the reamers is said to guarantee high performance, even for hard metals with a resistance more than 1200N/mm2. The Ilix carbide 6372C range of hundredth reamers is from 0.98mm through to 12.05mm in increments of 0.01mm. The reamers are manufactured to a tolerance of +0.000 - +0.004mm. The cermet reamers 6323 have new cutting geometry developed by Ilix. These reamers are said to be ideal for steel machining, having high chemical stability during the cutting process. They offer good wear resistance due to the high hardness and have low material adhesion. The Ilix cermet reamer is said to
