Introduction
Product Overview
The VEAM CIR Series connectors are highly versatile multipin connectors designed for harsh environments, originally developed for transit applications and now widely accepted in military, commercial, medical, geophysical, entertainment, nuclear, aerospace, and ground support sectors. They offer a robust and reliable interconnect solution, featuring a quick-disconnect coupling that surpasses MIL-DTL-5015 environmental requirements. The CIR connectors are known for their positive lock mechanism, stainless steel anti-wear rings, and are adopted as the standard connector for Ground Fighting Vehicles by NATO.
