Housing-Only Build — Order the Terminals Separately
At 2.50 mm pitch in a single row, it keeps the assembly narrow — handy when you're routing a 7-circuit bundle into a tight panel opening. The natural PA66 nylon housing carries a locking ramp on the mating face, so the plug stays put once it clicks into the matching receptacle.
What You're Actually Buying — a Housing, Not a Connector
The listing note spells it out: contacts are not included.
Mating and Locking — What It Pairs With
This plug mates with the Signal Double Lock receptacle housing (TE 1379217-6 is a 5-position example in white, but the 7-position receptacle is the direct match). The locking ramp on the plug engages a corresponding latch on the receptacle — you'll hear it click when fully seated. Free-hanging (in-line) mounting means no panel cutout or PCB footprint; the assembly floats in the harness, which is typical for appliance and automotive interior connections where the wire bundle takes the strain.
How It Stacks Against the 6-Position Sibling
If your BOM calls for 6 circuits instead of 7, the direct sibling is the 1-1376477-6 — same 2.50 mm pitch, same single-row layout, same locking ramp, but in a red PA66 housing. The only functional difference is the position count and the colour; the cavity spacing and terminal compatibility are identical. For a 6-wire harness, the 1-1376477-6 saves one cavity and one terminal, which matters when you're buying in volume and every crimp operation counts.
