The TE Connectivity 1746864-1 is a 24-position plug housing from the 0.64/2.3 series, designed for free-hanging (in-line) wire-to-wire or wire-to-board harness applications. It uses a 2.20 mm pitch between contacts and a 3.00 mm row spacing, with a locking ramp for secure mating in environments where vibration could work a connector loose.
What the 24-Position Count Means for Your Harness
With 24 positions across two rows, this housing matches a 24-circuit BOM line. The closest same-series sibling is the 1746863-1, which carries 26 positions at the same 2.20 mm pitch and 3.00 mm row spacing — if your circuit count is 26, that is the correct pull; for 24 circuits, this is the one. Both use the same locking ramp and accept the same crimp terminals, so the swap is a position-count decision, not a tooling change.
The 0.64/2.3 series uses a 0.64 mm tab on the mating header side; the receptacle terminal crimps onto the wire and locks into the housing cavity. For a complete mated pair, pair this plug housing with the TE header that carries the same 2.20 mm pitch and 0.64 mm tab.
