0.156" Pitch Receptacle Housing for SL-156 Harnesses
The TE Connectivity 1-640251-1 is an 11-circuit receptacle housing from the SL-156 series, designed for free-hanging wire-to-board or wire-to-wire interconnects.
This receptacle mates with the SL-156 series pin headers — look for the matching 0.156" pitch, single-row headers with 11 positions. The crimp termination accepts the standard SL-156 female socket contacts (sold separately, typically TE part numbers 640250-1 or 640250-2 depending on wire gauge). The primary latch on the housing side locks audibly when mated; the natural colour makes visual inspection of full seating straightforward on the line.
