Truck-Lite 50861 50 Series 7-Way Trailer Receptacle (7 Split Pin, Grey Plastic, Surface Mount)

Premium Split-Pin Design: Features 7 split-pin terminals made of high-conductivity, cadmium-plated brass. The split-pin geometry allows for a slightly tensioned, snug connection that adapts perfectly to male plugs, absorbing road shock and ensuring consistent contact.

Tough GE Noryl Plastic Housing: The rugged grey body is molded from heavy-duty GE Noryl plastic, which is entirely non-conductive, highly impact-resistant, and immune to rust, road salt, chemical exposure, and moisture damage.

Floating Contacts for Perfect Alignment: Equipped with "floating type" pins that adjust slightly during plug-in to eliminate terminal bending and premature wear on the electrical assembly.

Eliminates Wire-Strand Breakage: Uses secure ring terminal wiring connections internally. By avoiding harsh set screws, this receptacle completely prevents wire fraying and the resistance drops that cause intermittent lighting failure.

Direct-Wired Internal Grounding: Built-in dedicated ground wiring bypasses chassis-ground variables, preventing flickering lights and ensuring continuous power loop reliability.

Clear Circuit Mapping: Embossed notations and industry-standard color codes are molded directly into the housing to streamline installation and diagnostic troubleshooting.

SAE J560 Compliant: Built to meet strict industry standards, providing absolute compatibility with standard commercial 7-way tractor-trailer plugs.
