Xmost M12 L-coded male rear mount socket provides an external DC power connection with wire termination inside the equipment housing. Its rear fastened construction is intended for panels designed to accommodate the rear mounting hardware and internal harness.
This M12 male power connector offers five contact arrangements, allowing selection of circuit contacts with or without functional earth. The unwired solder version supports termination during assembly, while pre-wired versions provide a defined lead length for routing to an internal terminal or harness connection.
Choose this rear mount M12 L-coded socket according to panel access, wiring clearance and electrical requirements. The catalogue lists a rated current of 16 A, a rated voltage of 63 V and a wire size of 2.5 mm² / AWG14.

Needle Arrangement (Front View)
[Insert the five male contact arrangements from page 15 here.]
| Catalogue Configuration | Contact Composition |
|---|---|
| 3-pin (2+FE) | 2 circuit contacts + functional earth |
| 3-pin | 3 circuit contacts, without FE |
| 4-pin (3+FE) | 3 circuit contacts + functional earth |
| 4-pin | 4 circuit contacts, without FE |
| 5-pin (4+FE) | 4 circuit contacts + functional earth |
Use the mating-face diagram to identify the numbered contacts. FE-equipped and non-FE versions must be selected by their complete arrangement, rather than total contact count alone.
