Module Helps Drive Users Standardise Network


SM-EtherCAT extend the functionality of Control Techniques' variable speed drives, providing support for real-time, high-performance Ethernet communication. Control Techniques' Product Manager, System Integration Products, Imad Rajraji said 'EtherCAT is the first in our planned range of real-time Ethernet solutions with more protocols to follow'.

The module is for use with Control Technique's full range of AC and servo drives from 0.37kW simple conveyor or pump control, through high-precision servo applications and 1.9MW multimode drives.

This allows customers to standardise their network across the whole machine. The SM-EtherCAT module is the latest in a wide range of communication options that already include Ethernet/IP, Modbus TCP/IP as well as traditional fieldbus. EtherCAT is being requested by customers because of its excellent performance and bandwidth, allowing users to get good dynamic performance from their drives.

It covers the whole range of communication requirements from high-end motion control through to central factory computer control of conveyors and pumps. Control Techniques' SM-EtherCAT module can operate at cycle times down to 250us, synchronising the drive's position or speed loop to the communications network, improving overall system performance. Control Techniques now has 24 SM option modules, used to extend its I/O, feedback, communications, automation and motion capability.

All AC and servo drives use the same option module format allowing flexible connectivity and functionality with Digitax ST, Control Techniques' new servo drive, Commander SK, as well as Unidrive SP, which has a total of three internal option slots for modules.

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
