M12 L-coded female front mount socket provides the equipment-side connection for a compatible M12 L-coded male power cable connector. It mounts to the enclosure panel, with solder terminals or pre-wired leads connecting to the internal DC wiring.
Select the front fastened version when it matches the panel installation design. The unwired socket allows termination during equipment assembly, while pre-wired versions provide 0.1 m, 0.3 m or 0.5 m leads for routing to an internal terminal or harness connection.
Five contact arrangements are available. FE means functional earth. For example, 4+FE provides four circuit contacts plus one functional earth contact, giving five contacts in total. Select the arrangement according to the equipment schematic and mating connector.
2. Key Features
- 16 A / 63 V DC power connection: Match the electrical ratings to the equipment circuit.
- L-coded female interface: Connects to a compatible M12 L-coded male connector.
- Front fastened mounting: Select according to the panel installation drawing.
- Solder termination: Supports internal wire connection during assembly.
- Five contact arrangements: Choose versions with or without functional earth.
- Unwired or pre-wired: Terminate your own wires or use supplied leads.
- Three listed lead lengths: 0.1 m, 0.3 m and 0.5 m.
- PG9 or M16 × 1.5 mounting: Match the mounting thread to the panel opening.
