The 0.156" (3.96mm) pitch is the standard spacing for this series, matching the MTA-156 header footprint. The closed-end feature means the cable stops at position 8 — no pass-through for daisy-chaining.
Termination and Wire Gauge
The 26 AWG wire is pressed into the IDC slot, displacing insulation to make contact. No crimp tool or stripping step needed.
Mating and Compatibility
The 3-640430-8 mates with any MTA-156 header of the same 8-position count and 0.156" pitch — vertical or right-angle, through-hole or surface-mount. The single-row, free-hanging (in-line) mounting style means it terminates the cable end and plugs onto a board-mounted header. The closed end prevents the cable from extending past position 8, which matters if you're routing the harness tight to the board edge.
