M12 L-coded female rear mount socket connects an external male power cable connector to the equipment’s internal DC wiring. Select the rear fastened version when the enclosure provides the required mounting access and clearance for the rear hardware.
The unwired solder socket can be terminated during harness assembly. Pre-wired versions provide 0.1 m, 0.3 m or 0.5 m leads for routing to an internal terminal or harness connection.
Choose the contact arrangement according to the circuit conductor count and whether functional earth is required. FE-equipped and non-FE versions must be matched to the equipment schematic and mating connector.
Key Features
- Rear fastened installation: For panels designed around a rear mount receptacle.
- 16 A / 63 V ratings: For DC power circuits within the listed electrical limits.
- Female L-coded connection: Accepts a compatible M12 L-coded male connector.
- Solder wiring interface: Supports connection to the internal equipment harness.
- With or without FE: Five contact arrangements for different circuit requirements.
- Pre-wired lead selection: Listed lengths of 0.1 m, 0.3 m and 0.5 m.
- Two panel threads: PG9 and M16 × 1.5 versions.
- Unshielded design: As specified in the catalogue.

| Option | Circuit Contacts | FE Contact | Total Contacts |
|---|---|---|---|
| 2+FE | 2 | 1 | 3 |
| 3-pin | 3 | 0 | 3 |
| 3+FE | 3 | 1 | 4 |
| 4-pin | 4 | 0 | 4 |
| 4+FE | 4 | 1 | 5 |
The diagrams show the mating-face view. For example, 3+FE and 4-pin both have four contacts, but their contact arrangements differ.
