What This 2-Position Housing Is and Where It Goes
The 0.156" (3.96mm) pitch matches the footprint of the mating SL-156 header pins — common on power supplies, appliance control boards, and automotive interior modules.
The listing says "Contacts Not Included" — and it means it. This housing ships empty. If your BOM only lists the housing, the harness line stops when the assembler opens the bag and finds no pins. Add the terminals to the order before the RFQ closes.
Mating and Locking — What You Feel When It's Right
If it doesn't click, the housing isn't fully seated and the terminals can fret under vibration. The single-row, 2-position layout is keyed by the housing geometry itself; you can't insert it backwards against the header. Crimp termination means you use a hand tool or a press for the terminals, then push them into the rear of the housing until the retention tang locks. A tug on the wire confirms the terminal is seated.
