The 0.156\" (3.96mm) pitch matches the standard MTA-156 header footprint, and the single-row layout keeps the cable exit inline with the board edge. ## Termination and Wire Sizing It is sized for 24 AWG only; the slot geometry does not accept other gauges reliably. Tin is adequate for one-time assembly into a harness; for repeated disconnect-reconnect duty, the mating header should use tin contacts as well to avoid galvanic mismatch. The polarizing key ensures the connector cannot be inserted backward. For panel-feed applications, the closed end blocks the connector from passing through a cutout, which keeps the termination inside the enclosure.","metaTitle":"TE Connectivity 3-643820-7 MTA-156 Receptacle, 7 Pos","metaDescription":"TE Connectivity MTA-156 IDC receptacle, 7 positions, 0.156\" pitch, 24 AWG, tin contacts, locking ramp.
