The housing accepts crimp contacts (contact termination type is crimp), so the harness builder crimps the terminal onto the wire, then inserts it into the cavity until the latch locks. This is the most common sourcing pitfall on this part: the BOM line for the housing alone leaves the harness half-built. ## Mating and Termination — What It Connects To The free-hanging in-line mounting style means it terminates a wire harness and plugs into a panel-mounted or board-mounted counterpart. The latch lock engages audibly when fully seated — a field-service check that the connection is secure. For the wire side, use the specified crimp tooling for the Power Double Lock contact family.","metaTitle":"TE Power Double Lock 5-177903-1, 9-Pos Plug Housing, 3.96mm","metaDescription":"TE Power Double Lock 5-177903-1 plug housing, 9 positions, 3 rows, 0.156\" (3.96mm) pitch.
