Free-hanging (in-line) mounting lets the connector float in the harness, absorbing cable strain without a board anchor. The natural colour housing is the standard CT series moulding colour, no keying or colour-coding variant. ## IDC Termination — No Stripping, No Crimp Tooling IDC termination pierces the wire insulation as the contact is pressed into the housing slot, making gas-tight connection to the conductor. This eliminates the need for a separate crimp tool and wire stripper — a single hand-press or automated IDC tool seats all contacts simultaneously. The 26-28 AWG range is narrow; verify your wire diameter fits the slot width before committing the BOM.","metaTitle":"TE Connectivity 173977-2 CT Receptacle, 2-Pos, 2mm Pitch","metaDescription":"TE 173977-2 CT series 2-position IDC receptacle, 0.079\" (2.00mm) pitch, tin contacts, 26-28 AWG, free-hanging.
