The TE Connectivity 1969442-7 is a 7-circuit, single-row plug housing from the Economy Power 2.5 series.
It mates with the matching 2.50 mm pitch header from the Economy Power 2.5 series; the latch holder locks the pair together. The free-hanging mount means it's a field-repairable connector — you can re-pin it on site with a basic crimp tool if a terminal backs out or frets.
