Xmost M12 K-coded female rear mount PCB socket connects an external AC power cable to the circuit board inside industrial equipment. Its female interface receives a compatible K-coded male cable connector, while straight insertion contacts provide PCB dip-solder termination.
Designed for rear fastened installation, this M12 panel mount power socket suits enclosures with a defined panel-to-board position. The rear mount outline should be used to check mounting clearance and circuit-board placement.
Three configurations include protective earth: 2+PE, 3+PE and 4+PE. Each carries catalogue ratings of 16 A and 630 V, with PG9 or M16 × 1.5 mounting available.
Key Features
- Rear fastened construction: For housings designed around a rear mount panel power socket.
- Female M12 K-coded interface: Mates with compatible male AC power cable connectors.
- 16 A / 630 V ratings: Listed for all three contact arrangements.
- Protective earth included: Two, three or four circuit contacts plus PE.
- Direct PCB termination: Straight contacts support board insertion and dip soldering.
- Two panel thread options: PG9 or M16 × 1.5, in unshielded construction.
