M12 A-Coded Field-Wireable Plug for Sensor and Actuator Loops
The T4112001021-000 is an M12 A-coded plug with 2 female sockets, designed for field termination onto 4.00 mm to 6.00 mm cable. It carries a 4 A per-contact rating at 250 V, which is typical for powering and signaling proximity sensors, photoelectric cells, and valve actuators in automated machinery. The screw termination inside the backshell lets a panel builder or field tech terminate the wires without a crimp tool — just strip, insert, and tighten. The right-angle cable exit keeps the cordset close to the panel face in tight enclosures. The threaded coupling nut and O-ring seal at the mating face are what make that rating hold — the thread pulls the plug face tight against the receptacle seal.
What the 4 A and 250 V Ratings Mean for a 2-Position Plug
Two positions at 4 A each gives you 8 A total through the connector, which is enough for a single sensor or actuator drawing under 48 W at 24 VDC. The gold-plated mating surface (3.00 µin) handles the low-level signal contacts without fretting corrosion, even in humid industrial air.
Mating and Cable Fit
The cable opening accepts 4.00 mm to 6.00 mm cable. The screw terminals inside accept stripped wire ends; no crimp contacts are needed.
