The orange housing is a visual identifier on the harness, useful for tracing circuits in a panel. This connector is the wire-mounted half of a wire-to-board interconnect, commonly used in appliance, HVAC, and industrial control harnesses where fast IDC termination is needed. ## Termination and Wire Handling Cable termination is IDC — insulation displacement — so no wire stripping is needed. The receptacle accepts 18 AWG discrete or ribbon cable. ## Contact Finish and Duty","metaTitle":"TE MTA-156 3-643817-3, 3-Position IDC Receptacle","metaDescription":"TE MTA-156 3-643817-3 3-position IDC receptacle, 0.156\" pitch, tin contacts, locking ramp.
