The 26-28 AWG range covers common signal-level wire gauges used in control cabinets and appliance harnesses. A splice is a fault waiting to happen if the IDC tines don't fully penetrate the insulation; a proper press tool ensures the cover seats flush and the tines bite through cleanly. Free-hanging (in-line) mount means this receptacle floats in the harness — no board lock, no panel clip. It mates with the corresponding CT series pin header (male pins, same 2.00mm pitch). The natural (uncolored) housing is a visual cue for wire routing; no secondary latch or CPA is listed on this variant, so the friction of the IDC termination and the housing lock are what hold the pair together. For a harness that sees road buzz or machine vibration, confirm the mating header includes a locking ramp.","metaTitle":"TE 1-173977-1 CT IDC Receptacle, 11 Pos, 2.00mm Pitch","metaDescription":"TE 1-173977-1 CT series IDC receptacle, 11 positions, 0.079\" (2.00mm) pitch, tin contacts, 26-28 AWG.
