Description

The Y11 Series Circular Electrical Connectors are precision-engineered components designed to deliver reliable signal transmission in the most demanding operating environments. Developed in accordance with GJB 101A-97, this series offers exceptional compactness and versatility, making it the ideal choice for military and civil telecommunication systems where space is at a premium.

At its core, the Y11 Series utilizes a bayonet connection system that enables quick, quarter-turn mating—ideal for applications where speed and security are paramount, such as field-deployed military communication equipment or avionics systems. The contact system features solder-terminated pins in three diameters (Φ0.8mm, Φ1.0mm, Φ1.5mm), supporting rated currents from 3A to 10A and ensuring low contact resistance for stable signal transmission.

Engineered for environmental resilience, the Y11 Series boasts exceptional sealing capabilities: rubber-sealed sockets maintain a leakage rate of ≤60Pa·cm³/s at 0.2MPa, while glass-sealed sockets offer ultra-low leakage rates of ≤1×10⁻⁷Pa·cm³/s. With a wide operating temperature range (-55°C to 125°C), compliance with GJB101A-97 salt spray requirements, and insulation resistance exceeding 3000 MΩ, these connectors thrive in extreme conditions from arctic cold to desert heat, and from coastal saltwater to industrial humidity.

Available with multiple sealing types (rubber, glass-to-air) and installation methods (square flange, nut flange, through-wall), the Y11 Series offers unparalleled flexibility for integration into military communication systems, civil telecommunication equipment, and aerospace avionics.
