ITT Electronic Components claims that its VEAM CIR series multi-pin connector is one of the world's most versatile. The VEAM CIR series can function as an electrical, optical or pneumatic connector, and it is also available in high voltage, twin or tri-axial, hermetic and EMC versions.
Designed originally for the hostile environment of mass transit applications, CIR connectors are also suitable for use in industrial, military, commercial, medical, geophysical, entertainment, nuclear and aerospace applications. The design parameters were based on MIL-C-5015; however, its innovative positive-lock and quick-disconnect coupling surpasses the environmental requirements of this military specification. The CIR design has been adopted by NATO as the 'standard connector for Ground Fighting Vehicles' and is used extensively in USA and European military programmes.
Coaxial CIR connectors accept most popular RG cables. Fibre styles are available with single- or multiple-fibre termini. Devices can include a range of insert/grommet materials to provide superior resistance to fuel oils, solvents and elevated temperatures; alternatively they can be supplied with glass-to-metal hermetic seals in lieu of elastomeric inserts.
Other configurations include:
- Twin- or tri-axial - size 4 or 8 contacts
- RFI/EMI - grounding fingers on plug connectors provide superior plug-to-receptacle (360-degree) shield integrity. Filtered devices are also available incorporating tubular or planar filter networks
CIR connectors have also been designed for pneumatic operation. Various insert arrangements with size 4, 8 or 12 cavities accept contacts to pass liquid or air at pressures of up to 7.6bar (110psi). Flow valves are additionally available.
Finally, CIR connectors are available with various thermocouple material contacts including chromel, alumel, copper, constantan and iron.
