Loop Powered Isolator to 3 KV

August 28, 2007 10:32 am | Comments

OTEK releases its model LPI opto-isolated loop powered transmitter that uses no transformers and choppers that reflect noise on the transmitter’s line. The transmitter uses a special technique to convert the incoming 4 mA to 20 mA frequency to drive the opto-isolator. The device comes in a miniature plastic case (metal on request) that can be din-rail mount, Velcro attached or in line with existing wiring.VDC and Hertz I/O options are also available.The LPI is useful in hazardous applications as an isolator or buster

Punch Down Blocks Field Terminate AWG 22-26 cabling in CAT 6a and CAT 7 Applications

August 28, 2007 9:58 am | Comments

Stewart Connector released the SS-51 series of punch down blocks engineered to allow the field termination of insulated AWG 22-26 solid copper wire in Category 6a as well as in Category 7 applications in which wires are individually shielded. The RoHS-compliant parts employ Insulation Displacement Contact technology, they allow for rapid mass termination of multiple wires in state-of-the industry telecom and datacom systems. The blocks boast a notched-head design to secure the wires in the plastic housing prior to termination to ensure a mechanically stable connection between the conductor, and terminating contact

35W Power over Ethernet PD Controller

August 28, 2007 7:45 am | Comments

Linear Technology introduces the LTC4268-1, a Power over Ethernet (PoE) interface controller with a synchronous, current mode, switching regulator for delivering precise regulation and high efficiency to power-hungry Powered Devices (PDs). The device provides up to 35W for 2-pair systems and as much as 70W for 4-pair systems. The IC features a high-performance switching regulator optimized for isolated PoE applications, and it incorporates the company’s NoOpto feedback topology to provide full IEEE 802.3 isolation without the need for optoisolator circuitry

Two-Port Interface Master Card

August 28, 2007 7:37 am | Comments

The eAutomation Group of Advantech introduces its PCI-1202U PCI interface card with two AMONet master ports that support the company’s AMAX line of motion and control products. It is a hybrid RS-485 based network similar to other proprietary fieldbus networks intended to offer high speed deterministic communication. Common CAT5 cable is the recommended medium, making it appropriate for distributed motion control applications.

Position Tracking System Has Fraction-of-a-Millimeter Feedback

August 28, 2007 7:34 am | Comments

Pepperl+Fuchs added the WCS3B Read Head to its PosiTrack Position Tracking System. Designed to provide simplified installation and improved operational performance, this read head provides a 32 mm slot width, compared with the 25 mm slot width available from the existing WCS3A model. The result is increased reader/code rail misalignment tolerances of 20 percent on the horizontal axis and 40 percent on vertical axis.
