The 3-641216-4: The 0.295" (7.49 mm) mating pin length gives the receptacle contact beam enough wipe to establish a clean connection. The 4-position single-row layout is loaded on all positions — no empty holes to account for in the harness design.
Gold Mating Finish and Friction Lock — Fit for Repeated Mating
The friction lock holds the mated receptacle in place against vibration and cable tug. No secondary TPA here, but for a 4-position signal connector it's enough retention for most fixed-equipment harnesses.
Mating and Termination — What Connects Here
This header mates with TE MTA-100 IDC receptacles (e.g., 3-640428-4) or crimp-socket housings that accept 22-26 AWG discrete wire. The single-wall shrouding guides the receptacle into alignment but leaves one side open — check the orientation before stuffing the harness. The square pins provide good solder fillet formation on the through-hole pads.
Available through independent distribution channels. The bulk package suits production runs; reel or tray options are not listed for this variant.
