The TE Connectivity RITS 4-1746741-3 is a 3-position, single-row female socket for discrete wire, terminated via IDC (insulation displacement). The housing is black and ships in tube packaging.
Termination is IDC — the wire is pressed into insulation-displacing slots, so no separate crimp terminal or tooling is required beyond a simple press. Accepts 20-26 AWG discrete wire, which covers typical signal and low-current power leads in control and sensor harnesses.
The single-row, 3-position layout is keyed by the housing geometry to prevent mis-mating with different circuit-count headers.
