Resistors

Enhanced pulse and overload

The PWC series of resistors is available in sizes 0805, 1206, 2010, and 2512, with respective power ratings of 0.125, 0.33, 0.75, and 1.5W. The ratings are up to 50% higher than standard thick-film chip resistors, the company says. Working voltages of the larger sizes (400V in the 2010 and 500V in the 2512) are double conventional limits. The products have no special heat sink requirements.

Tilt sensor

Ideal for down-hole logging

High-precision T435 inertial tilt inclinometers are reportedly rugged enough for harsh outdoor environments. The closed-loop, gravity-referenced sensors are available in a variety of ranges, with solder pin terminations. Applications include borehole mapping, dam and rock shifts, satellite dish alignment, weapons sighting, tilting train control, and civil engineering analysis.

VME modules

Processors share local memory

A four-processor, high-performance VME board has two expansion module sites: the velocity interface mezzanine and PCI mezzanine card. The board has four MPC7410 PowerPC processors providing as much as 16 gigaFLOPS of floating-point signal processing power. Boards have built-in front-panel 10/100 Ethernet and RS232 interfaces. Applications include radar, sonar, signal intelligence, and image processing. Pentek Inc. www.pentek.com Enter 586

High-performance sockets

IC guide with fingers included

ZIF 10 GHz bandwidth sockets are designed to guide the IC into exact position Sockets support very dense BGA devices using elastomer contactors. They are mechanically mounted to the PCB and have a smaller footprint than other sockets. The socket body and heat sink screw are aluminum to help heat-sinking. One example, the VF-BGA356L Intel® Xscale™ processor, is used in handheld applications. Ironwood Electronics www.ironwoodelectronics.com Enter 587

Automotive sensors

Multi-operational, compact

Specialized for automotive applications, MST system sensor chips offer safety and reliability in airbags, seatbelt tensioners, and antilock brakes. Sensors about the size of pinheads provide information on pressure, temperature, emissions, and other physical variables. Intelligent control systems and stability programs are two of the newest automobile designs that use MSTs. Bosch Rexroth Co. www.boschrexroth-us.com Enter 588

3-mm PCB LEDs

Red, green, or yellow

A series of right-angle, 3-mm PCB LEDs is reportedly ideal for automated positioning machinery where precise alignment of status indicators is required. Available in bi-level, tri-level, and quad-level, the LEDs withstand sock, vibration, frequent switching, and environmental extremes, the company says. Lasting 20 times longer than incandescent lamps, LEDs have an average life of 100,000+ hours. LEDtronics Inc., www.ledtronics.com Enter 589

Chip sets

Improved thermal characteristics

Two synchronous buck MOSFET chip sets are designed to increase battery life and reduce device on-resistance. The sets minimize conduction loss, reduce gate charge, and reduce gate-to-drain charge. Reportedly ideal for Vcore power in the Intel® Centrino™ processor, IRF7821 and IRF7832 improve efficiency over the load range. IRF7821 features a 40% reduction in gate charge, while the IRF7832 improves device on-resistance by 25%, the company says. International Rectifier www.irf.com Enter 590

Circuit breakers

Replace fuses in blocks

These circuit breakers are designed to reduce downtime by replacing the fuses in DIN-rail terminal blocks. The 1180 Series plugs into standard blocks and protects plant equipment at 250V ac or 65V ac. Breakers can be reset immediately after faulting and prevent use of the wrong replacement fuse. The units are 8 mm wide and reportedly avoid nuisance tripping during harmless, short surges, such as in-rush current. E-T-A Circuit Breakers www.etacbe.com Enter 591

Crimp splices

Shrinks above 150F

PolyCrimp heat-shrinkable crimp splices join two wires in a butt splice configuration using a one-piece, adhesive-lined sleeve with a seamless crimp barrel. Rated for 66V ac, crimps shrink at about 2:1 and insulate the butt, while protecting from environmental factors. Crimps are color coded for wire size, from 22 to 10 AWG, in 3 sizes. Applications include automotive aftermarket, marine, traffic control, pair, and maintenance. Tyco Electronics Power Componentswww.circuitprotection.com Enter 592

Ultrasonic sensors

For bottling, small containers

Quick setup and consistent performance are considered two benefits of the S18U Series compact ultrasonic sensor. These products feature push-button programming, diagnostic status LEDs, and a factory-adjusted ultrasonic beam. Available in straight or right-angle, the 18-mm barrel design offers many mounting options. The sensors are made of ABS plastic and rated IP67 and NEMA 6P.

Cable assemblies

Ideal for industrial, medical uses

Polarization-maintaining cable assemblies are made of single-mode fiber that preserves the polarization of light as it travels. They are precisely aligned to mechanical or optical planes. Ideal for telecommunications switching and multiplexing, PM assemblies are also used in industrial and medical applications. PM fiber can be terminated in industry standard connectors.

Machine vision system

15 digital input lines

The LabVIEW-based, NI CVS-1454 compact vision system makes cameras smarter and handles multiple camera inputs, according to the manufacturer. Three IEEE 1394 ports allow connection of various imaging sensors. Two on-board software versions — NI Vision Builder for automated inspection and LabVIEW — offer developers flexibility to switch between the two and migrate data.

Sensor input module

Decrease device count

The 1762-IR4 4-channel resistance temperature detector module connects the company's model 1200 controller to platinum, nickel, nickel-iron, and copper RTDs. The product eliminates the need for expensive thermocouple transmitters, the company reports. This module reads temperatures in C or F, with resolution to tenths of degrees. The sensor range is -200 to 850C. Applications include industrial and process control, pharmaceutical, petrochemical, and transportation. Allen-Bradley www.rockwellautomation.com Enter 596

Inductive sensors

Ideal for in-die sensing

Unlike many designs using steel endcaps, the SteelFace™ inductive sensor body is milled from one piece of solid stainless steel. Impact and abrasion resistant, SteelFace sensors withstand up to 500 psi of dynamic pressure and are available in ferrous-only and nonferrous-only models. Typical applications are aluminum machining, sensing tool pallets, and cutting tools and fixtures while ignoring the bulk of aluminum chips. These items are available in 8-, 12-, 18-, and 30-mm sizes, and withstand wash-down applications to 1,200 psi. Balluff Inc. www.balluff.com Enter 597

Stainless steel cordsets
