Nano Micro Quadlok Receptacle, 20 Circuits, 1.80mm Pitch
It uses a 0.071" (1.80mm) pitch across two rows, keeping the footprint small while delivering multi-circuit connectivity. The housing is black and free-hanging (in-line), terminated via crimp contacts — you supply the wires and the matching female socket terminals. This receptacle carries a Connector Position Assurance (CPA) feature — a secondary lock that engages after the primary latch lock clicks home.
As a female socket receptacle with crimp termination, the 2312120-1 requires the matching male header from the Nano Micro Quadlok series (sold separately) and the correct crimp terminals. The latch lock provides primary retention; the CPA feature adds a secondary lock that prevents the latch from being accidentally released — critical in applications where the connector is routed near moving parts or subject to snagging. The free-hanging (in-line) mounting style means this receptacle is wired into a harness, not soldered to a board. The 2-row, 20-position layout at 1.80mm pitch demands careful wire routing to avoid crowding the terminals during crimp insertion. Use the TE-specified crimp tooling for the Nano Micro Quadlok terminal family to get consistent pull-force and avoid terminal push-back.
