The 0.156" (3.96mm) pitch is wider than typical 2.54mm headers, giving more room per circuit in the harness — useful for power distribution or larger-gauge wire routing.
Contacts are ordered separately — don't miss this
Common compatible terminals include the TE 640250 series (e.g., 640250-1, 640250-2) for 18-22 AWG wire.
Mating half: the SL-156 header
This receptacle mates with the SL-156 series pin headers — typically the 640245 or 640246 family in straight or right-angle through-hole configurations at the same 0.156" pitch. No secondary lock or screw is required; the ramp provides the retention.
