MINNEAPOLIS, MN–Omnetics Connector Corp. (www.omnetics.com) has developed increasingly smaller nano connectors targeting space and weight-critical military applications.
The Circular Nano series, says Omnetics, is one of the smallest circular connector families that use a MIL-quality contact system. With a total mated length of 9.0 mm and outer diameters ranging from 3.1 to 5.5 mm, the connectors are designed for extremely harsh operating environments, including medical, military and aerospace applications.

Manufactured to ensure electrical integrity while withstanding temperature variations from -55° to +125° C, as well as extreme vibration, the Circular Nano connectors feature polarized hard gold-plated contacts shrouded in a proprietary liquid crystal polymer housing designed to MIL-M-24519, making them capable of more than 2,000 mating cycles. Featuring a proprietary Flex-Pin contact system, the Circular Nano connectors are spaced on 0.64-mm centerlines and are available in 6-, 11-, 16- and 28-position housing sizes, with either pre-wired or solid straight-tail terminations.
Omnetics has also recently designed a new series of miniature polarized nano connectors for military, aerospace, defense, and medical applications. Insulators are designed to hold one row of pins and one row of sockets, which polarizes the connector without the space typically required for guide pins.

“These connectors prevent mis-mating, and save space and width in critical applications, such as military avionics and satellite systems, ensuring signal integrity even in conditions where high shock and vibration are present,” says Gary Evans, Omnetics’ European sales manager.
The connectors are able to withstand temperature ranges of -55° to 125° C (200° C with high-temperature epoxy). Available in 4-, 6-, 8-, 10-, and 12-position sizes, these polarized devices are on a 0.635-mm pitch spacing, and feature gold-plated contacts. Rated at 1 amp per contact, with a maximum contact resistance of 25 mW (71 mV) @ 1 amp, these polarized nanos are designed with an insulation resistance of 500 MW minimum at 100 volts DC. 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, and horizontal or vertical surface-mount. CS
