J14A Rectangular Connector

Compliant with GJB142A-94, this compact, lightweight rectangular connector features a highly reliable, quick-locking mechanism. It is primarily designed for aerospace/satellite systems, launch vehicles, and ground support, while widely applicable to various electronic instruments, meters, and cable interconnections.

Main Features & Specifications:

• Low-frequency
• Double-safety locking mechanism
• Rigid pin and socket structure
• Termination types: Solder and PCB tail connection
• Rounded-corner polarization design to prevent mismating
• When the termination type is solder cup, the solder hole diameter is Φ0.6mm. The recommended wire core cross-sectional area for soldering is 0.15mm², but it should not exceed 0.2mm². When the termination type is solder pin, the solder pin diameter is Φ0.6mm.
