TE Connectivity introduced a micro circular plastic connector (CPC) capable of accommodating between twelve and nineteen contacts. This new offering, based on a 13.5 shell size (13.5/16ths of an inch diameter), expands upon the previously released micro CPC which accommodated up to seven contacts in a 9.5 shell size. With the additional contact positions, designers can optimize the I/O efficiency of the system they are designing. The low-cost design provides excellent performance too. This new, higher pin-count design is suitable for applications in medical equipment, instrumentation and industrial equipment.

Micro CPC connectors are available in wire-to-wire, wire-to-board or wire to panel versions. Two contact systems are available. A spring-probe contact arrangement is available for high reliability applications such as medical equipment, high-cycle instrumentation and test & measurement equipment. Spring probe contacts are screw machined and provide a redundant current path. They are rated for up to 5,000 mating cycles.

For lower mating cycles, a precision screw machined pin and socket contact system is available. With the pin and socket arrangement, up to 500 mating cycles are possible. The pin and socket contact system provides the reliability and cost effectiveness necessary for many disposable medical device applications. Both contact styles have gold-plated finishes.

Micro CPC connectors have a squeeze-to-release feature which provides easy disconnection while maintaining a positive latch. The single-piece, nylon housing provides good resistance to chemical agents and also provides environmental sealing up to IP65. Contacts are rated for up to three amps at 250 VAC maximum.


  • Squeeze-to-release coupling mechanism offers positive latch or optional breakaway locking feature
  • Panel mount receptacle offers jam nut mounting
  • Keyed and polarized
  • Sealed to IP-65
  • No assembly required
  • No application tooling required


  • Ideal for medical, instrumentation, and industrial applications where size, contact density, and durability are primary concerns
  • The nylon housing offers good resistance to a wide range of chemical agents while the IP-65 sealing prevents ingress of dirt or fluids that would have an adverse effect on the contact interface
