The 0.156\" (3.96mm) pitch matches the standard MTA-156 header footprint, making this a direct mate for the corresponding pin header in the same series. The closed-end housing acts as a positive stop for the cable during insertion, preventing over-insertion that could damage the IDC slots or leave exposed conductors. The orange color is a visual identifier on the assembly line — MTA-156 housings come in several colors, and this one tells the technician they're working with the 12-position variant at a glance. ## Wiring and Termination Notes This receptacle terminates via IDC — the 18 AWG wire is pressed into the insulation-displacement slot, which pierces the insulation and makes contact with the tin-plated phosphor bronze beam. The IDC slot is sized for 18 AWG only; forcing 20 AWG into the same slot will result in a loose fit and intermittent contact. The free-hanging (in-line) mounting means the receptacle floats in the harness, aligning to the header during mating without a panel cutout.","metaTitle":"TE MTA-156 4-640431-2, 12-Pos IDC Receptacle, 0.156\" Pitch","metaDescription":"TE MTA-156 4-640431-2 receptacle, 12 positions, 0.156\" pitch, IDC termination for 18 AWG wire.
