San Marcos, Calif. Sullins Electronics has expanded its edgecard connector portfolio with the release of a high-temperature, dual-readout series that accepts 0.093-inch (2.36 mm) thick daughtercards. Made of high-density dielectric materials, parts may be ordered to withstand 150 degrees C continual heat.
The connectors may be used in a variety of industrial, consumer, and commercial applications such as electronic component testing, communication, medical equipment instrumentation, and automotive R&D. They are uniquely suitable for use in power converters, power supplies, and test and burn-in ovens where thicker daughtercards are frequently used to minimize warping on larger backplanes, said Sullins.
The UL/ cUL recognized connectors feature high-density 0.050-inch (1.27 mm) contact center spacing and easily replace 0.100-inch (2.54 mm) center spacing parts to double the number of contacts within the same area. They are supplied in straight, card extender, and right-angle configurations.
The series is manufactured with BeCu (beryllium-copper) contacts and PA9T insulators for applications with a temperature range of -65°C to +150°C, or with phosphor-bronze contacts and PA9T insulators for use in -65°C to + 125°C temperature applications. Provided with 6 to 100 contact positions, they offer a mated signal contact bulk resistance (daughtercard mated to backplane module) of 30 milliohms maximum.
Other features include an insulation resistance of 5,000 Megohms minimum at 125 Vdc, a single contact current rating of 3 amps, and a signal contact normal force of 75 grams minimum. Selective gold or overall gold plating, along with customization is available.
