Sullins Electronics has expanded its edgecard connector portfolio with the release of a high-temperature, dual-readout series that accepts 2.36mm thick daughtercards. Made of high-density dielectric materials, parts may be ordered to withstand 150C 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 1.27mm contact center spacing and easily replace 2.54mm 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 beryllium-copper (BeCu) contacts and PA9T insulators for applications with a temperature range of -65C to 150C, or with phosphor-bronze contacts and PA9T insulators for use in -65C to 125C temperature applications. Provided with 6 to 100 contact positions, they offer a mated signal contact bulk resistance (daughtercard mated to backplane module) of 30m maximum.

Other features include an insulation resistance of 5,000M minimum at 125Vdc, a single contact current rating of 3A, and a signal contact normal force of 75g minimum. Selective gold or overall gold plating, along with customization is available.

Pricing ranges from 35 cents to 65 cents per contact pair in production quantities.

Delivery is three to four weeks ARO; Samples are immediately available.
