Axial analog data transfer system for high-voltage isolation up to 20 kV at 32 mm

The OPI1270 series is an axial optical isolator designed to provide electrical isolation and data transfer. The device consists of a visible red LED emitter and a phototransistor detector housed in separate opaque molded plastic housings and coupled by a shrouded optical cable that gives the device extremely high-noise immunity. The isolators are offered with standard lengths of 32 mm, 40 mm, and 80 mm, and can be produced in custom lengths up to 10 m or longer. Applications include industrial, medical, and office equipment, as well as electrical isolation circuits in harsh environments.

The series is rated for a minimum of 20 kV isolation for the 32 mm device, and carries a power dissipation rating of 100 mW. The AlInGaP LED (emitter) emits red light with a peak wavelength of 645 nm, with on-state collector current ranging from 0.9V to 1.5V (IF=20mA), and maximum collector dark current of 80 mA (VR=3.0V).

The phototransistor (sensor) exhibits a maximum collector current of 50 mA (VCE=10V, EE=0). Collector-emitter breakdown voltage is 33V (min.), and emitter-collector breakdown voltage is 5.5V (min.) (both measured at 100mA, EE=0). The current transfer ratio for the device is typically 10% with a LED current of 20 mA. The operating temperature range is -20°C to +85°C, and the device is also compatible with high-temperature soldering processes of 260°C.

Compact UV sensor for limited space and difficult application environments

The UVX-300G-REM is a UV (ultraviolet light) luminescence sensor that is designed to combine small size with long range, high-resolution, and ease-of-use in demanding applications. The device has a remote sensing head that is easily mounted and measures 0.7 in. x 0.8 in. x 1.2 in., a volume of less than 0.7 in.³. The sensor’s technology is intended to produce high sensitivity and long-range target detection that is more reliable than many other vision systems. The sensor head can be positioned near rollers and spray nozzles, while the unit’s long detection range allows positioning away from debris contamination and physical damage.

The UVX-300G-REM is suited for detecting adhesives applied in assembly, manufacturing, and packaging operations. The output of the remote sensor head is connected to a control unit through a 1 m cable. The sensor control unit provides a visual readout and sends signals (0V to 5V analog and discrete on/off) to a master controller through a separate cable. As part of a feedback control loop, the sensor is designed to precisely measure the amount of applied adhesive, check for the presence of a material or part, and alert operators to problems such as misapplication, omitted items, and improper equipment operation.

New metal dome stacking procedure

Snaptron, Inc., manufacturer of metal tactile domes and dome arrays, has developed a procedure for “stacking” metal domes supplied on adhesive tape (Peel-N-Place arrays). The stacking domes allow the ability to double the actuation force of any of Snaptron’s four-leg domes sizes 7 mm to 20 mm. Actuation forces in excess of 4,000 g can now be achieved on standard and custom dome arrays with adhesive.

Typically, the life of a dome diminishes as the actuation force increases in relation to the size of dome. The result is that design engineers have often had to sacrifice actuation force in order to achieve their desired life. Stacking domes are designed to allow higher forces to be achieved with little or no impact on life.

Smart power relay for the transportation industry

E-T-A Circuit Breakers offers the E-1048-8D (E-1048 Dice) Smart Power Relay, a remotely controllable electronic load-disconnecting relay matching standard four-pin automotive relay sockets. The E-1048 Dice is a replacement of standard protection concepts and uses an electromechanical relay in combination with a blade fuse to provide electronic over-current protection in a compact unit.

The relay is suited for shock and vibration applications within the transportation industry because of its wear-resistant switching function. It is also intended for applications where contact deterioration can occur due to frequent switching of inductive loads in road, rail, and marine vehicles.

The E-1048 is designed to operate at temperatures of -40ºC to +85ºC (-40ºF to 185ºF) without the need for derating. Additionally, it requires only a fraction of the control power needed by electromechanical relays (approximately 5 mA) and has a low current consumption (less than 1 mA). Both fractional control power and low current consumption make the E-1048 Dice suited for battery-buffered, on-board electrical systems.

Measuring 30 mm x 30 mm x 30 mm, the relay is available in DC 12/24V, nine current ratings, and two basic versions.

Miniature molded case circuit breakers

Moeller has just expanded its FAZ line of miniature circuit breakers to include devices that are listed and certified as molded case circuit breakers per UL 489 and CSA 22.2, No. 5-02. These current-limiting branch circuit breakers, called FAZ-NA, are suited for the protection of power supplies, control power transformers, HVAC, refrigeration equipment, florescent lighting (to 20A), and many other applications requiring a primary protective device.

The circuit breakers are available in one-, two-, and three-pole configurations with 20 different current ratings ranging from 0.5A to 40A, enabling fuseless solutions for smaller loads. All breakers are available in both C and D tripping curves. Two- and three-pole devices can be used in solidly grounded circuits up to 480 VAC. The line offers short-circuit ratings of 10 kA regardless of voltage applied.

The devices are current-limiting, meaning they interrupt fault currents within one half cycle of the fault. Current-limiting devices are designed to offer superior protection by reducing peak let-through current and energy. This line is available in two terminal configurations: standard box terminals that accept multiple conductors, and ring-tongue terminals that are suited for the semi-conductor industry. All breakers mount on standard 35 mm DIN-rail. Bus connectors and feeder terminals facilitate mounting and wiring of multiple miniature circuit breaker arrays in control panel assemblies.

APPLICATION X-TRA

Industrial e-commerce goes to sea

When you're at sea with your $4.5 billion aircraft carrier and you need a pressure transducer — quickly — for your list control system, where do you turn for 24/7 support? The Internet, of course.

Rob Matthes, president of Transducers Direct LLC and a Navy veteran himself, learned this while handling the 24-hour service calls for his company. A sailor aboard the Nimitz-class Abraham Lincoln called from "somewhere at sea" late on a recent Thursday night. The Navy man had found the pressure transducer he needed for the ship's list control system on the Transducers Direct website, and he wanted one, plus a spare, shipped out post haste.

"They needed a non-standard pressure port of 9/16 in., so we could not ship same day as we normally would, but we built the transducer on Friday based on their verbal order and waited for their final instructions while they worked out delivery issues at their end," Matthes says. "We got the formal order by email Saturday and later exchanged several calls and emails with them on their shipping requirements."

The specific product needed was Transducers Direct's stainless steel TDG 01 transducer configured for vacuum to 85 psi. It uses CVD sensing technology to produce measurements with ±0.15% linearity and provides a 0V to 10V or 4 mA to 20 mA output.

"On Monday we overnighted the products to Pearl Harbor, where they were put aboard a plane bound for the carrier," says Matthes. "It was really gratifying to us to provide a small piece of support to such a great warship in a pinch situation. We've supplied other ships in port a few times in the past, such the USS Champion and USS Devastator, where we upgraded them to new linear transducers for rudder control, but we've never been called by a ship at sea. We would have loved to learn more about how our transducer fits into the carrier's list control system, but it was almost as interesting to see just how powerful the Internet is."
