Proximity Sensors

Solves battery operated problems

These load dump inductive proximity sensors reportedly withstand both 12 and 24V electrical transient surges, passing five SAE tests including Pulse 1 and Pulse 5A. Sensors are designed to offer solutions to high voltage transient problems that affect large vehicles using battery-operated systems like garbage trucks, lift equipment, and military vehicles.

Power relay

Low profile, long mechanical life

This low profile, high-power relay is rated for high ambient temperatures (-40 to 105C) for use in audio-visual equipment, home appliances, office automation, and industrial HVAC applications. Measuring 29 x 12.7 x 15.7 mm, the relay offers a mechanical life of more than 20 million operations, a 10 kV surge withstand, and a dielectric strength of 5,000V ac between coil to contacts and 1,000V ac between contacts. According to the company, the relay comes with 250 and 400 mW power coils. Fujitsu Components America Inc., www.fcai.fujitsu.com Enter 577

Relay and coupler

AC switching, control components

The company's Solid State Relay (SSR) and Phototriac Coupler feature ac switching and control components for appliance, HVAC, industrial and manufacturing equipment markets. The PC2 and PC3 lines of DIP-4 and DIP-6 Phototriac Couplers offer low power and triggering current as low as 3 mA, in addition to noise immunity. The 8-pin DIP SSRs, with both zero-cross and non-zero cross type, are designed for small power requirements. Sharp Microelectronics of the Americaswww.sharpsma.com Enter 578

Digital multimeters

Hands-free operation

The XR-Series DMMs consist of five ergonomically designed models intended for electricians, electronics technicians, field service troubleshooters, design testers, and industrial plant managers. The basic 30XR DMM features a built-in non-contact voltage detector and "data hold," while the more advanced 38XR DMM has true-rms, backlight, CAT III 1,000V, CAT IV 600V range, and RS232 capability. The 33XR, 34XR, and 37XR DMMs in between vary in cost and features. Wavetek Meterman Test Toolswww.metermantesttools.com Enter 579

Low DP transducer

Protects against incorrect wiring

The PX2650 Series low differential-pressure transducer, intended for use in HVAC ducts and clean rooms, reportedly protects against incorrect wiring and can operate from an unregulated power supply. Available water columns range from 0.25 to 100 inches in unidirectional and bi-directional ranges. Operable in temperatures ranging from 40 to 150F, the transducer features accuracy specifications of ±1% BFSL at constant temperature. OMEGA Engineering, www.omega.com Enter 580

Cable assemblies

For automotive telematics

IDB IEEE 1394 (Intelligent Data Bus) Consumer Convenience Port connectors consist of hot pluggable cable assemblies and corresponding PCB-mount receptacles. Cable assemblies are available in lengths up to 10m and in four versions: bilingual plug to beta plug, bilingual plug to bilingual plug, bilingual plug to IEEE 1394 AV plug, and bilingual to IEEE 1394-95 plug. The fully shielded right angle PCB-mount socket is designed to withstand 7,500 mating cycles. Lumberg Inc.www.lumbergusa.com Enter 581

Automated programming system

Fast Flash programming

The PS Infinity^™ Series Automated Programming System, engineered for high-volume tape-to-tape device programming, is reportedly the fastest Flash programming system. The system is available with a high-speed handler and two configurations capable of testing, programming, and verifying up to 3,000 or 5,000 devices per hour, respectively. Applications include automated inline, automated offline, and manual programmers. Data I/O Corp.www.dataio.com Enter 582
