Airtight connectors

Cinch Connectors has added hermetically sealed, commercial off-the-shelf micro-D connectors to its Duracon family featuring twist-pin contacts, combining airtight performance with enhanced electrical integrity and high resilience to shock and vibration.

The connectors achieve hermeticity 1 x 10^-8 cc/s at 1 ATM in helium and match the vibration performance of the company’s unsealed COTS micro-D connectors, which exceed MIL-prf-83513.

The connectors are available in standard configurations from nine to 100 pins and use Duracon in their construction featuring gold-plated copper-alloy contacts, aluminium shell and UL94V-0 flame-retardant insulator.

In addition to the internal hermetic seal, a fluoro-silicone outer O-ring, and jack posts against bulkhead/panel/enclosure, seal the mating contacts and allow easy installation without welding, brazing or soldering.
