The TE Connectivity MTA-156 4-640599-0 is a 10-position single-row IDC receptacle, part of the MTA-156 family known for mass-termination of discrete or ribbon cable. It accepts 18 AWG wire and terminates via insulation displacement — no wire stripping, no crimping, just a one-step press. The 0.156" (3.96mm) pitch gives enough spacing for 18 AWG without crowding the IDC slots, and the locking ramp holds the mated pair together in a control cabinet or panel harness. The orange housing is a visual key for the MTA-156 series — grab the right color, you've got the right pitch.
Termination and Wire Handling
The feed-through feature allows daisy-chaining wires through the connector, useful for bus-style wiring in lighting or sensor arrays. Free-hanging (in-line) mounting means it lands in a harness, not on a board.
That ramp is the difference between a connector that stays put under vibration and one that walks loose. Single-row, 10 positions — match the position count to the header, and you're set.
