M12 A-Coded Panel Receptacle, 2-Position, Solder Cup
The T4130012021-000: The A-coding ensures it mates only with A-coded M12 cordsets — the standard for sensor and actuator networks in industrial automation. Rated 4A per contact at 250V, the current is carried by gold-plated copper alloy pins with a 3.00µin gold mating finish, sufficient for the moderate mating cycles typical of a field-installed sensor drop. The shell is nickel-plated copper alloy, the insert is PA66 nylon 6/6 rated UL94 V-0, and the sealing gasket gives IP67 protection when mated — dust-tight and protected against temporary immersion to 1 m.
Termination is solder cup — you strip, tin, and solder each conductor directly into the cup. The threaded fastening ring mates with any standard M12 A-coded female cordset; the IP67 seal engages when the coupling nut is torqued to the manufacturer's specification. There is no secondary terminal position assurance (TPA) — the contact retention relies on the solder joint and the insert. For a field-replaceable connector, the 2-position count keeps wiring simple: pin 1 is typically brown (24V), pin 3 is blue (0V), per the M12 A-coded standard.
