WM Type — High-Density Miniature Connectors

WM Type High-Density Miniature Connectors

The WM Type connector series represents the pinnacle of miniaturization in military-grade interconnects. With contact pitches as fine as 0.635mm, WM Type connectors pack more connections into less space than any other Russian-standard connector line. Ideal for next-generation compact military systems, UAVs, soldier-worn electronics, and miniaturized satellite subsystems.
