J14 Series

Our J14 series connectors feature a dual locking mechanism (J14A, B, C, D, G, M, P) that combines quick operation with reliable connection security. These rectangular connectors are designed for welding termination and are widely used in strategic weapon systems, aerospace satellite systems, launch vehicles, ground support systems, as well as various electronic instruments, meters, and cable connections.

J14A: Air tight socket connector, typically mating with ordinary plug connector
J14B: An improved version over model J14A, available with rainproof features and more densely arranged contacts. J14B also comes with an electrical cable whose specification and length will be determined by customers.
J14E: Double locking mechanism, square shell with rounded corners
J14F: Push pull connector with crimp contact
J14H: Double locking mechanism, compact design, densely arranged pins, solder contact
J14P: Screw-on connector with either 90° or straight-through cable entry, and solder contact
J14M: Low-magnetic connectors
