Power Triple Lock Plug Housing, 12 Circuits
The TE Connectivity 5-1971876-4 is a 12-position plug housing from the Power Triple Lock, High Temp series. It uses a 6.00 mm pitch across three rows, with a row spacing of 8.10 mm, giving each power blade enough room for the rated creepage. The housing accepts female blade socket contacts terminated by crimp, and the latch holder fastening locks the pair together — the audible click confirms the mate is secure against road buzz or machine vibration.
Mating and Termination
This plug housing mates with the corresponding Power Triple Lock header (not included). The latch holder provides the secondary lock — friction alone won't hold the road buzz. Contacts are not included with the housing; order the matching female blade socket crimp terminals separately. The crimp termination requires the correct tooling for the wire gauge specified in the terminal datasheet.
