The TE Connectivity 281783-8 is an 8-position IDC plug in the HE13/HE14 series, terminated to discrete 24-26 AWG wire via insulation displacement. The 0.100" (2.54mm) pitch and single-row layout match the standard HE13/HE14 header footprint — a common choice for internal board-to-wire harnesses in control panels, test equipment, and low-current signal distribution where the IDC process replaces individual crimping.
The 0.100" (2.54mm) pitch is the same as legacy 0.1" grid headers — no footprint surprise if you are replacing a similar IDC connector. The detent lock holds the plug to the header without a secondary latch — enough for moderate vibration inside a cabinet, but not rated for high-shock or outdoor use. Free-hanging (in-line) mounting means this is the cable-end half; the board-side mate is a through-hole header with matching 0.100" pitch. No crimp tool needed, but the wire must be solid or stranded with a consistent OD; ribbon cable is not supported.
