The CIR/FRCIR Series is the most versatile electrical, optical and pneumatic multipin connector available today. Designed originally for the hostile environment of Transit applications, CIR/FRCIR has earned acceptance in Military, Commercial, Medical, Geophysical, Entertainment, Nuclear, Aerospace. Ground support and comparable areas requiring nearly non-destructible cable or wire terminations. The electrical design parameters of CIR/FRCIR were based on MIL-DTL-5015. However, its unique positive lock, quick disconnect coupling surpasses the environmental requirements of this military specification. To enhance service life, CIR/FRCIR connectors feature stainless steel anti-wear rings at the critical point of the receptacle coupling ramps. The CIR/FRCIR design has been adopted by NATO as the “standard connector for Ground Fighting Vehicles” and is used extensively in U.S. and European military programs: Based on standard VG 95234.
