Sullins Electronics expanded their edgecard connector portfolio to include a high-temperature, dual-readout series manufactured to accept 0.093” (2.36 mm) daughtercards. The cards are supplied in straight, card extender, and right angle configurations. Their UL/cUL connectors feature high-density 0.050” (1.27 mm) contact center spacing and replacable 0.100” (2.54 mm) center spacing parts to double the number of contacts within the same area. Each connector has 6 to 100 contact positions, mated signal contact bulk resistance of up to 30 mO, insulation resistance of 5,000 MO minimum at 125V DC, single contact current rating of 3A, and signal contact normal force of 75g minimum. The phosphor-bronze connectors withstand temperatures of -65°C to 125°C, while optional beryllium-copper connectors can handle up to 150°C. Gold plating is another option. Conventional reflow soldering is the intended design choice. Uses include power converters, power supplies, and test/burn-in ovens, where thicker daughtercards help minimize warping on larger backplanes. Typical pricing ranges from $0.35 to $0.65 per contact pair.
