Description

The YMHH Series Circular Electrical Connectors are precision-engineered components designed to deliver reliable signal and power transmission in the most demanding operating environments. Developed in accordance with GJB2446A-2004, this series offers exceptional compactness and versatility, making it the ideal choice for military, aerospace, and industrial systems where space is at a premium.

At its core, the YMHH 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 four diameters (Φ0.8mm, Φ1.0mm, Φ1.5mm, Φ2.5mm), supporting rated currents from 3A to 25A and ensuring low contact resistance for stable signal transmission.

Engineered for environmental resilience, the YMHH Series boasts exceptional sealing capabilities and excellent moisture, salt spray, and fungi resistance. With a wide operating temperature range (-55°C to 125°C) 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 installation methods (square flange, nut flange, through-wall) and housing plating options (shielded, unshielded), the YMHH Series offers unparalleled flexibility for integration into military communication systems, avionics, field operation equipment, and industrial control systems.
