The green, closed-end housing carries tin-plated female sockets and uses a locking ramp for positive retention with the mating header. ## Wiring and Termination — IDC Fit The IDC termination accepts 28 AWG wire — either discrete strands or ribbon cable. The insulation displacement contacts pierce the wire insulation in a single press operation, which saves crimp time on multi-conductor harnesses. The closed-end feature means the back of the housing is sealed, preventing wire poke-through. ## Pitch and Position Count — Board Layout Fit At 0.100\" (2.54mm) pitch, this 13-position receptacle matches the standard MTA-100 header footprint. The single-row layout keeps the board-edge width to about 1.3 inches.","metaTitle":"TE MTA-100 4-640443-3 Receptacle, 13 Pos, 0.100\" Pitch, IDC","metaDescription":"TE Connectivity MTA-100 4-640443-3 receptacle, 13 positions, 0.100\" pitch, IDC termination, tin contacts, locking ramp.
