M12 A-coded female rear mount socket connects a compatible external male cable connector to the equipment’s internal harness. Choose the rear fastened version when the enclosure provides mounting access and clearance for the rear hardware.
The unwired M12 female solder socket allows termination during harness assembly. The 0.3 m pre-wired version provides leads for routing to an internal terminal or circuit connection point.
Select the contact count according to the required conductors, then check its current, voltage and wire size. Higher-contact-count versions have different electrical ratings, so the chosen configuration must match the equipment circuit.
Key Features
- Rear fastened installation: For panels designed around a rear mount receptacle.
- Female A-coded interface: Mates with a compatible M12 A-coded male connector.
