Durable multipin connector ITT CANNON 51511-16-20T12 quick disconnect coupling meeting MIL DTL 5015 standards

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 a robust and reliable interconnect solution 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 utilized in numerous U.S. and European military programs, based on standard VG 95234. Key features include stainless steel anti-wear rings for enhanced service life, fuel resistance options, hermetic sealing capabilities, high voltage variants, RFI/EMI shielding, thermocouple contacts, and pneumatic capabilities. These connectors are engineered for nearly non-destructible cable or wire terminations. ### Product Attributes
