Product details

Board-to-Wire Header for MTA-156 Harnesses

It carries 4 positions on a 0.156" (3.96mm) pitch, mates with MTA-156 receptacles, and uses a friction lock to keep the pair engaged under vibration.

Pitch, Positions, and Locking Fit

The 0.156" (3.96mm) pitch is the standard for MTA-156 wire-to-board systems — the same spacing as the receptacle. The 4-position, single-row layout is fully loaded (all positions populated). The shrouded 1-wall design provides basic keying to prevent mis-mating.

RoHS3 compliant. The header ships in bulk packaging.
