12-Position Power Triple Lock Plug Housing for Harness Builds
The TE Connectivity 1-1971776-6 is a 12-position, dual-row plug housing from the Power Triple Lock, Standard series. The housing is free-hanging (in-line) and terminates via crimp contacts — the latch holder fastening locks the mated pair against vibration, making it suited for harness assemblies in automotive, industrial, and appliance environments where the connector sees mechanical shock. The glass-filled PBT body handles an operating range of -55°C to 150°C, so it can sit underhood or inside an industrial cabinet without derating the housing material.
Contacts Not Included — Order Crimp Terminals Separately
This housing ships without contacts — the female blade socket terminals must be ordered separately and crimped onto the wire before insertion. The contact termination is crimp, so the wire gauge and terminal must match the housing cavity. Confirm the compatible TE crimp terminal part number for your wire size before committing the BOM line.
Mating Half and Keying
The 1-1971776-6 mates with the matching Power Triple Lock receptacle housing of the same circuit count and pitch. The latch holder on the plug engages the receptacle's locking ramp for a positive, audible click during assembly. The natural colour and keyed geometry prevent mis-mating with other series in the same panel.
