Panel-Mount Power Receptacle, 9 Positions at 0.250" Pitch
The TE Connectivity 1-1604254-1 is a 9-position receptacle from the Universal MATE-N-LOK series, designed for panel-mount wire-to-wire or wire-to-board power interconnects. The 0.250" (6.35mm) pitch and matching 0.250" row spacing give this three-row housing a square contact pattern that fits standard cutouts for bulkhead or chassis feed-through applications.
Locking Ramp and Panel Fit
The locking ramp fastening type is the key mechanical detail here: it engages with the matching plug's latch to create an audible, tactile lock when fully mated. In a panel-mount installation — the receptacle snaps into a rectangular panel cutout — this ramp holds the pair together against cable tug and machine vibration without requiring a secondary screw or clip.
Mating and Termination
This receptacle mates with the corresponding Universal MATE-N-LOK plug housing (sold separately) that carries male pins. The crimp termination means you select the appropriate female socket terminal for your wire gauge — typically 20-14 AWG for the standard power contact in this series — and crimp it onto the wire before inserting it into the housing cavity. The locking ramp on the receptacle and the latch on the plug are the only retention; there is no secondary terminal position assurance (TPA) in this basic housing, so full insertion and a pull-test on each contact is the field practice.
