What the A-Code and 5 Positions Mean for Your Harness
The T4141012051-000 is a TE Connectivity M12 A-coded circular plug with 5 female sockets, intended for sensor/actuator signal and low-power distribution in industrial automation. The A-coding orientation is the standard for DeviceNet, IO-Link, and most 5-pin sensor interfaces — a B-coded or D-coded receptacle will not mate, so confirm the mating half carries the same A-code keying. The 5 positions at 4 A per contact give you four signal lines plus a shield ground or a fifth power return, depending on the pin assignment.
IP67 Sealing and Panel Mount — Where This Plug Belongs
The bulkhead-front-side-nut mounting lets you fasten it through a panel cutout from the outside, with the threaded coupling ring securing the cable side. The nickel-plated copper alloy shell and PA66 insert (UL94 V-0) resist the cutting fluids and solvents common in machine-tool environments.
