Xmost M12 L-coded male rear mount PCB connector links an external DC power cable to the circuit board inside industrial equipment. Its threaded male interface accepts a matching L-coded female connector, while straight rear contacts provide the internal board connection.
The rear fastened construction suits enclosures designed around a rear mount panel interface. Use the corresponding outline drawing to check housing clearance and the position of the PCB relative to the panel.
Choose 2+FE, 3-pin, 3+FE, 4-pin or 4+FE according to the circuit requirements. All configurations carry catalogue ratings of 16 A and 63 V, with functional earth included only in the designated FE versions.
Key Features
- Rear fastened installation: For housings requiring a rear mount M12 power connector.
- 16 A / 63 V DC interface: Listed ratings across the available configurations.
- Five contact arrangements: Three to five total contacts, with or without FE.
- Male L-coded connection: Mates with the matching female power cable configuration.
- Direct PCB termination: Straight insertion contacts support dip soldering.
- Two mounting threads: PG9 or M16 × 1.5 in unshielded construction.
