8-Position Plug Housing for the Dynamic D-3100 Series
The 3.81mm pitch is wider than a typical signal connector — it accommodates larger-gauge crimp terminals rated for power distribution rather than low-current signal paths. A polarizing key on the housing ensures the plug only mates with the matching receptacle in the correct orientation, which prevents mis-mating in multi-connector harnesses.
The Dynamic D-3100 series uses a standard crimp contact that terminates discrete wire, then inserts into the housing cavity. Without the terminal part number on the BOM, the line stops. Confirm the wire gauge and the specific TE crimp terminal for the D-3100 series before committing the build.
Crimp Termination and Free-Hanging Assembly
The free-hanging (in-line) mounting type means this plug is part of a cable harness, not a board-mounted header. The housing has no board locks or solder tails; it mates with a panel-mount or free-hanging receptacle. The single-row, 8-position layout keeps the harness narrow, which helps in tight routing through conduit or along a chassis rail.
Polarizing Key and Housing Construction
The polarizing key is a molded feature on the housing that aligns the plug with the matching receptacle — it prevents a reversed or incorrect mate in a multi-connector system. The housing material is a thermoplastic polyester, glass-filled (UL94 V-0 rated by series default), which handles the thermal load of power contacts without softening.
