The TE Connectivity 1-172169-9 is a 9-position, 3-row plug housing from the Mini-Universal MATE-N-LOK series, designed for free-hanging (in-line) wire-to-wire or wire-to-board harness applications. The 4.20 mm pitch gives enough spacing for 20-16 AWG crimp terminals without crowding the cavity walls, and the latch lock keeps the mated pair together under vibration — a solid choice for automotive engine compartments, industrial control panels, and appliance wiring where a connector isn't going to be unmated every week.
What Fits in This Housing
The 1-172169-9 accepts both male and female crimp contacts (sold separately), terminated with standard crimp tooling for the Mini-Universal MATE-N-LOK family. The housing is molded from black PA66 (Nylon 6/6) rated -20°C to 105°C, which covers most underhood and industrial enclosure environments without a derating headache.
