Housing for a 7-Circuit SL-156 Harness
The TE Connectivity 640250-7 is a 7-position receptacle housing from the SL-156 series, designed for wire-to-board or wire-to-wire harnesses where the 0.156" (3.96mm) pitch matches legacy power and signal layouts. The natural nylon body carries a locking ramp that gives a positive audible click when mated with the matching SL-156 header, holding the pair together under vibration in industrial control cabinets or appliance wiring.
What You Need to Order Alongside It
This housing ships without contacts — the Note on the line reads Contacts Not Included, so a separate line item for the SL-156 female crimp socket terminal is required to populate the 7 cavities. The contact termination is crimp, and the free-hanging (in-line) mounting means the housing floats in the harness rather than locking to a panel. For a field-service swap or a new build, confirm the terminal part number for your wire gauge before the crimp tooling arrives.
Mating Half and Fit Check
The 640250-7 mates with the SL-156 series pin header — typically a through-hole or right-angle header with the same 0.156" (3.96mm) pitch and 7 positions. The locking ramp on the receptacle engages the header's ramp slot, so a header without the matching slot (some unshrouded versions lack it) won't latch.
Sourcing and Lifecycle
No official cross-reference from Molex or JST exists, so a form-fit-function swap would require pitch, position count, and locking ramp geometry to match exactly.
