It uses the 0.156\" (3.96mm) pitch standard to the MTA-156 series, with a single row of tin-plated female sockets. The closed-end housing prevents wire over-insertion and provides a positive stop during assembly, while the integral locking ramp secures the mate to the matching header. ## Tin Plating and IDC Termination The IDC termination displaces the insulation and cold-welds to the conductor, making it suitable for high-volume harness production. The 20 AWG wire gauge is the specified size for this receptacle; using the correct wire diameter is critical for the IDC slot to bite properly and maintain contact force. ## Mating Header and Locking Ramp This receptacle mates with the standard MTA-156 header (e.g., TE 640441 series), which carries the same 0.156\" pitch and locking ramp feature. The yellow housing color aids visual identification in multi-wire bundles, a common practice in MTA-156 harness assemblies.","metaTitle":"TE MTA-156 4-640427-2, 12 Pos IDC Receptacle, 0.156\" Pitch","metaDescription":"TE MTA-156 4-640427-2 12-position IDC receptacle, 0.156\" pitch, 20 AWG, tin plating.
