M12 A-coded male rear mount socket connects a compatible external female cable connector to the equipment’s internal harness. Select the rear fastened version when the enclosure provides mounting access and clearance for the rear hardware.
The unwired M12 male 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.
Choose the contact count according to the required conductors, then check its current, voltage and wire size. A higher contact count has different electrical ratings, so the selected configuration must match the equipment circuit.
Key Features
