Engineered for high density circuitry capabilities, these connectors are designed to operate at temperatures ranging from -85°F to +392°F (-65°C to +200°C). They are readily adaptable to both commercial and space age requirements where size, weight, scoop proof/low-profile design and high reliability are key factors. The KJLY and KJAY are designed with a “scoopproof” feature which provides a safety factor in blind mating applications. The shells also feature five keyway shell polarization to assure alignment during engagement. Complete environment sealing is accomplished with an interfacial seal, with individual raised tapered sealing barriers around each pin contact, a peripheral seal, and hermetic sealing. ITT Cannon’s MIL-C-38999 KJLY, KJY and KJAY connector series offers these advanced features to meet the demands of present-day sophisticated engineering designs.
