Description

The Y50EX Series Circular Electrical Connectors are precision-engineered components designed to deliver reliable performance in the most demanding operating environments. Developed in accordance with GJB598A-96 (MIL-C-26482) T series standards, this series offers full interchangeability with JY, YB, and MS series connectors, making it the ideal choice for aerospace, marine, and power systems where legacy compatibility and modern performance are required.

At its core, the Y50EX Series utilizes a bayonet connection system that enables quick, quarter-turn mating—ideal for applications where speed and security are paramount, such as aircraft avionics or shipboard navigation equipment. The contact system features solder-terminated pins in five sizes (22#, 20#, 16#, 12#), supporting rated currents from 1A to 25A and ensuring low contact resistance for stable signal and power transmission.

Engineered for environmental resilience, the Y50EX Series boasts exceptional sealing capabilities with a socket sealing pressure of 0.2MPa, providing protection against moisture, dust, and salt spray. With a wide operating temperature range (-55°C to 125°C), excellent moisture and fungi resistance, and insulation resistance exceeding 5000 MΩ, these connectors thrive in extreme conditions from arctic cold to desert heat, and from coastal saltwater to industrial humidity.

Available with multiple housing materials (stainless steel, aluminum alloy, copper alloy) and installation methods (flange, cable, through-wall, screw-in), the Y50EX Series offers unparalleled flexibility for integration into legacy and modern systems alike.
