The manufacturer says its M12 series (M-metric/12mm circular connector industry standard diameter) with A-coding, or keying, prevents mismatching with other M12 versions. A-Code M12 connectors are most often used for sensor communication and carrying DC power.

The M12 A-Code series offers both IDC and soldering termination options for quick and easy installations, replacements, or upgrades. All of Stewart Connector’s M12 products are IP67 rated when installed, adding to the reliable nature of these connectors in industrial environments.
