Xmost M12 C-coded female rear mount socket provides an external cable interface with solder connections inside the equipment housing. Its rear fastened construction suits panels designed to accommodate rear mounting hardware and internal wiring access.
This M12 C-coded panel mount connector is available in four contact configurations. Current and voltage ratings vary by configuration, allowing selection against the requirements of the connected circuit.
Choose an unwired version for customer termination or pre-wired leads to reach the internal harness connection. Confirm the female contact arrangement, mounting thread and installation clearance before ordering.
Key Features
- Rear fastened construction: For equipment panels designed around a rear mount receptacle.
- Female C-coded interface: Mates with a compatible M12 C-coded male connector.
- Four contact arrangements: 2+PE, 3+PE, 4+PE and 5+PE options.
- Solder wiring connection: For termination to the internal equipment harness.
- Lead length selection: Unwired, 0.1 m, 0.3 m and 0.5 m versions listed.
