Introduction
Product Overview
The VEAM CIR Series connectors are versatile multipin connectors designed for harsh environments, originally developed for transit applications and now widely accepted in military, commercial, medical, geophysical, entertainment, nuclear, and aerospace sectors. They offer reliable interconnect solutions with a quick-disconnect coupling that surpasses MIL-DTL-5015 environmental requirements. The CIR series is adopted by NATO as the standard connector for Ground Fighting Vehicles and is used extensively in U.S. and European military programs, based on VG 95234 standards. They are suitable for electrical, optical, and pneumatic applications, providing robust and nearly non-destructible cable or wire terminations.
