6-Position Power Triple Lock Plug Housing
The TE Connectivity 1-1971776-3 is a 6-position plug housing from the Power Triple Lock, Standard series. It is a free-hanging (in-line) connector with a 6.00 mm pitch and dual-row layout, designed for wire-to-wire or wire-to-board power interconnects in harness assemblies. The natural PBT (glass-filled) housing carries a latch holder for secure mating and operates from -55°C to 150°C, suiting automotive, industrial, and appliance environments where thermal cycling and vibration are present.
The 6.00 mm pitch and 0.319" (8.10 mm) row spacing provide clearance between circuits.
Contacts Are Ordered Separately — Plan Your BOM
This housing ships without contacts — the note "Contacts Not Included" means you must order the matching female blade socket crimp terminals separately.
The 1-1644055-3 is a 6-position plug housing in the same Power Triple Lock family but with a 6.35 mm pitch and 6.35 mm row spacing, versus the 6.00 mm pitch and 8.10 mm row spacing of the 1-1971776-3. The 1-1644055-3 also carries a Glow Wire Compliant feature and ships in a Box package rather than Bulk. If your application requires glow-wire compliance or a wider terminal pitch, the 1-1644055-3 is the alternative; otherwise the 1-1971776-3 offers a tighter board footprint.
