CPC and CMC are available with a wide variety of accessories for added protection and reliability. CPC accessories include sealing and protective caps to protect unmated panel mounted connectors. Jacketed cable seals provide an environmentally sealed connection for jacketed cable. Cable entry seals and heat shrink boots provide environmental sealing and protection where the wires enter the rear of the connector shell. They are used with a jacketed cable and threaded onto the rear of the connector and then applied with a heat-shrink gun. Rubber boots that slide over the jacketed cable against the back of the connector provide "splash-proof" protection. Cable clamps provide strain relief and are used with discrete wire and jacketed cable. Panel mount flanges allow for the plug half to be mounted to a panel when required by the application. Keying plugs are used to prevent mismating when all of the available positions are not being used. Sealing and protective caps, cable entry seals or heat shrink boots, and keying plugs are available for CMC connectors.
