M12 A-Coded Plug, 4-Pin, IP67 — Field-Attachable Male Connector
The Molex 1200768034 is a Brad Safety Micro-Change 120076 series M12 A-coded plug with 4 male pins, gold-plated contacts, and a threaded coupling nut. The IP67 rating means the mated pair is dust-tight and protected against temporary water immersion — suited for washdown environments, machine tool enclosures, and outdoor junction boxes. The M12-4 shell size uses the standard M12 x 1.0 thread, so it mates with any standard M12 A-coded receptacle or cordset.
Threaded Coupling and Sealing — Vibration and Washdown Rated
The threaded fastening (M12 x 1.0) locks the plug to the receptacle with a positive mechanical grip — no accidental disconnection under machine vibration. The nickel-plated brass shell and polyurethane (PUR) insert resist industrial oils and coolants. The IP67 seal holds when the connector is fully mated and the coupling nut is torqued to the manufacturer's specification. Operating temperature from -25°C to 90°C covers most indoor industrial cabinets and outdoor enclosures in temperate climates.
4A per Contact, 250V — Sensor and Actuator Power
Rated 4A per contact at 250VAC/DC, this plug handles the power requirements of most industrial proximity sensors, photoelectric cells, and solenoid valves. The gold-plated mating contacts (Copper Alloy base) provide corrosion resistance and maintain low contact resistance over repeated mating cycles — important for field-service connectors that see frequent disconnect/reconnect. The 4-position count matches the standard M12 A-coded pinout (1: brown, 2: white, 3: blue, 4: black) used in 4-wire sensor cables.
