The Molex 2078410007 is a 7-circuit receptacle housing from the L1NK 250 series, built for wire-to-wire or wire-to-board harness applications where a positive latch and a compact 2.50mm pitch keep the assembly together under vibration. It's a free-hanging (in-line) housing — no PCB mount — so you crimp the terminals onto the wires, stuff them into the cavities, and the latch lock clicks the pair shut. The 2.50mm pitch is the same spacing used across the L1NK 250 family, so the matching header or plug will have the same centerline — no footprint mismatch if you're swapping into an existing harness that already uses this series.
Contacts — what's in the bag and what isn't
You get the empty housing, the latch lock, and the bag — no crimp terminals. That's standard for this class of housing; the terminals are ordered separately as a line item because wire gauge and plating grade (tin vs gold) depend on the current and environment the harness sees. For a 7-circuit build, you'll need seven female socket crimp terminals that fit the 2.50mm cavity pitch — typically the Molex L1NK 250 crimp terminal family. If you're re-pinning an existing harness on site, this is the part you grab when the old housing cracked or the latch broke — but you need to carry the loose terminals and a crimp tool to finish the job. No soldering, no special fixtures; a basic ratchet crimper for the 2.50mm terminal will do it.
Mating half and latch
This receptacle mates with the corresponding L1NK 250 header or plug that carries the male pin terminals, same 7-position count and 2.50mm pitch. Under vibration, that latch is what keeps the pair from walking apart; if you've ever had a connector back out on a conveyor line or a vehicle harness, you'll appreciate the positive lock. The single-row layout means the wire exit is in-line with the housing — no right-angle bend, so the harness lays flat. That's useful when you're routing into a tight conduit or along a frame rail.
