XRC sealed, plastic-circular connectors meet the demanding requirements of the non-automotive transportation market

Never before has Molex offered such an economical, rugged, sealed, circular connector. The XRC (Extra Rugged Circular) 14- and 31-circuit (18 and 24 shell size), circular connectors are ideal for heavy-duty applications such as trucks, buses and agricultural markets. For maximum design flexibility, the XRC plugs and receptacles are available in standard and reverse gender. The connectors can be used for in-line or panel-mount applications.

A backshell is available for use with the 24-shell size products. The backshells easily snap onto the XRC housing after terminal assembly to aid in the mating and unmating of the connectors. Unique notches on the collar of the connector line up with corresponding features in the backshell for maximum grip. In addition, the notches ensure the backshell stays in place while turning the connector, so the backshell is not spinning freely around the connector.

Designed to meet IP67 standards, XRC plugs and receptacles protect against the ingress of dust, water and other contaminants to maintain the integrity of the mated pair. Plugs feature a quick-disconnect bayonet latch to provide quick and easy connections with reduced installation and service time while ensuring accurate mating depth.


  • Marine - Boats and propulsion systems
  • Agriculture - Equipment, combines and tractors
  • Transportation - Tractor trailers, buses and fire trucks
  • Recreational Vehicles
  • Construction Equipment - Fork lifts, loaders, cranes, dump trucks and concrete trucks

Features & Benefits:

  • Low insertion force stamped terminals are economical and reduce connector housing mating force
  • Wire seals are imprinted instead of embossed or engraved (24-shell size, 31-circuit connectors only) making them easier to see and identify each circuit for faster installation and field servicing
  • Backshells have unique notches on the collar and easily snap onto the XRC housing (for 24/31 connectors only) for increased strain relief
  • Environmentally sealed to IP67 standard and protects against the ingress of dust, water and other con-taminants to maintain the integrity of the mated pair
  • Standard and reverse terminal genders allow for custom polarization
  • Bayonet-style latch provides quick and easy connections for reduced installation and service time as well as ensures proper depth when mated
  • Seal retainer collar is compatible with backshell and overmolding applications
  • Tactile and audible mating feedback facilitates reliable mating
  • Visual markings on outer shell allow for visual alignment to facilitate easier mating
  • Simple crimp-and-poke technology does not require terminal alignment when installing crimped wires
