What sets this housing apart in the Power Double Lock family is the sealed construction with a double lock plate. The seal keeps moisture and dust out of the contact cavity — useful for outdoor equipment, washdown areas, or anywhere a standard unsealed housing would let contamination creep in. The double lock plate adds a secondary retention feature that holds each terminal in place after crimping, so a partially seated contact won't back out under vibration.
Pitch, Rows, and the Mating Half
The 3.96mm pitch and 2-row layout mean this housing mates with the corresponding Power Double Lock header — look for the male pin header with the same 3.96mm pitch and dual-row configuration. The 4.60mm row spacing is wider than the pitch, which helps with routing traces between rows on the PCB side. Compared to the 6-position 1-2069882-6 from the same series, the 1971600-1 gives you two more circuits in the same dual-row format. Both use the same 3.96mm pitch and free-hanging crimp termination, so the decision comes down to position count matching your BOM. If your harness needs 8 circuits, this is the one; if 6 circuits fit, the 1-2069882-6 is a drop-in alternative with the same sealing and locking features.
The base product number is 1971600, so any variant with a different position count or color will share that prefix.
