  • Interchangeable with cPCI COTS Systems
  • Immune to shock and vibration fretting
  • High-temp LCP insulator meets NASA outgassing requirements
  • Reverse Gender to commercial 2mm Products
  • Keying feature ensures proper mating

Smiths Connectors cPCI 2mm connector system is based on the legendary Hypertac® contact technology, which is known for its’ immunity to shock and vibration fretting. Tested to military standards, the cPCI 2mm connector delivers the highest performance in a ruggedized CompactPCI format for all mission critical applications such as military land systems, shipboard, and aerospace.

Configured on a 2mm center-line with six rows, this connector uses 0.4mm Hypertac contacts that feature less than eight milliohms of contact resistance and a current rating of 1.0A. Our optimized contact lead traces provide superior performance in high-speed signal applications, and these connectors are compatible with standard reflow soldering processes.

The cPCI 2mm connector is available in both keyed and unkeyed configurations. Modular in design, the connector is variable in length and can be changed in increments of five contacts.

Other benefits include:

  • Hypertac contacts provide high reliability
  • Standard 2mm footprint
  • Shield prevents EMI/RFI

* Testing was performed to determine if fretting occurs due to mechanical motion and to evaluate the integrity of   the Hypertac contact system under severe shock. To validate the test, event detection was performed at 10  nanoseconds.
There were no events recorded.

** Testing was performed using a 6U Flight Chassis to determine if fretting occurs  due to mechanical motion and to evaluate the integrity of the test samples relative to severe mechanical environment. To validate the test, event detection was performed at 50 nanoseconds.
