As an authorized partner of HL (Taixing Yuhang Electronics), MXTD is proud to present the Y50EX Series Circular Electrical Connectors—the high-reliability interconnection solution engineered to meet the rigorous demands of aerospace, marine, and power applications. Designed in strict adherence to 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 system upgrades and legacy equipment support.
Crafted for durability, the Y50EX Series features a robust bayonet lock mechanism for rapid, secure mating and a versatile housing material selection (stainless steel, aluminum alloy, copper alloy) that ensures exceptional corrosion resistance in salt spray and high-humidity environments. With a wide operating temperature range of -55°C to 125°C and a sealing performance of 0.2MPa, these connectors deliver unwavering performance in the harshest conditions from deep-sea navigation to high-altitude avionics.
Backed by MXTD’s deep expertise in military-grade interconnection systems and global supply chain, we provide end-to-end solutions for the Y50EX Series, including custom contact configurations and cable assemblies. Every unit undergoes rigorous environmental and electrical testing to ensure compliance with GJB598A-96, making it the trusted choice for your critical connection needs.
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.
