October 22, 2008: Omnetics Connector Corp., a manufacturer of miniature high-rel connectors, is now offering a series of miniature polarized nano connectors for military, aerospace, defense and medical applications where size and weight are critical. The insulators are designed to hold one row of pins and one row of sockets, which polarizes the connector without the space normally required for guide pins, making these among the smallest polarized high reliability connectors in the world.

“These connectors prevent mis-mating and save space and weight in critical applications such as military avionics and satellite systems, ensuring signal integrity even in conditions where high shock and vibration are present,” says Greg Jones, sales manager, North America. “In addition, they are able to withstand temperatures as low as -55°C and as high as +125°C (200°C with high temperature epoxy).”

Available in 4, 6, 8, 10, and 12 position sizes, these new polarized devices are on a .025″ (.635mm) pitch spacing and feature gold-plated contacts. Rated at 1A per contact, with a maximum contact resistance of 25mΩ (71mV) @ 1A, the connectors feature an insulation resistance of 5000MΩ minimum at 100Vdc. Insulator material is thermoplastic polyester, type GLCP-30F to MIL-M-24519. Sockets are made of copper alloy and pins are beryllium copper. Termination options include pre-wiring, straight tail, horizontal surface mount and vertical surface mount.
