The TE Connectivity 1-350766-9 is a 3-position plug housing from the Universal MATE-N-LOK series, built for free-hanging inline wire-to-wire or wire-to-board connections. It's a single-row housing that accepts either male or female crimp contacts — you supply the terminals separately since contacts are not included. The latch lock on the housing gives a positive audible click when mated to the matching receptacle, holding the pair together against vibration in an industrial cabinet or on a piece of shop-floor equipment. The black nylon body handles the -55°C to 105°C range, so it's at home in an unheated warehouse or a warm control panel.
