M12 A-Coded Plug for Sensor and Actuator Networks
It sits in the T41450 series of M12 circular connectors, all sharing the same A-coded keying, IP67 sealing, and 4 A per-contact rating — the position count is what differentiates one member from the next. The nickel-plated copper-alloy shell provides EMI shielding, and the threaded fastening compresses the panel seal when mated with the matching cordset.
4 A at 60 V — Signal-Level Power, Not Bus-Level
Rated 4 A per contact at 60 V, this plug is sized for powering sensors, actuators, and field I/O modules — not for driving a motor or a main DC rail. The 5-position count matches the standard M12 A-coded pinout for a sensor with power, ground, and three signal or configurable lines.
Right-Angle PCB Termination at the Panel Wall
The plug mounts to a bulkhead via a rear-side nut and terminates to a PCB through right-angle solder tails. This places the PCB parallel to the panel face — a common layout in I/O junction boxes, valve manifolds, and control cabinet walls where the connector must seal at the panel and the board sits just behind it. The board lock and board guide features help register the connector during wave or hand soldering and take shear off the solder joints when the mating cordset is tightened.
Shielded Shell for Industrial Noise Environments
The copper-alloy shell with nickel finish provides a continuous EMI path to the panel ground when the plug is mated and the bulkhead nut is torqued. In motor-drive cabinets, inverter-fed machinery, or any area with switched-mode power supplies nearby, the shielding bleeds common-mode noise before it couples into the signal contacts. The IP67 rating means the seal holds against coolant spray, washdown, and dust ingress — the threaded coupling nut must be fully engaged to compress the O-ring.
5-Position vs 4-Position — The Only Selection Gate
The T4145035051-001 (5 positions) and the T4145035041-001 (4 positions) share every other spec: both are A-coded, shielded, IP67, gold-flash contacts rated 4 A, with the same nickel shell and right-angle PCB termination. The circuit count is the sole decision — match the BOM line's position requirement. The unshielded variants T4145015051-001 (5 pos) and T4145015041-001 (4 pos) drop the EMI shielding for cost-sensitive runs where the enclosure provides the ground plane.
