The wire type is discrete, not ribbon cable, so each conductor is routed individually through the harness. ## Mating Half and Housing Fit The closed-end feature means the housing is fully enclosed on the wire-entry side, which keeps debris out of the IDC slot during handling. Free-hanging (in-line) mounting lets it sit anywhere along the harness without a board mount.","metaTitle":"TE MTA-156 3-640426-7, 7-Position IDC Receptacle","metaDescription":"TE MTA-156 7-position IDC receptacle, 0.156\" pitch, 18 AWG discrete wire, tin plating 80.0µin, locking ramp.
