It carries IEC and cUL approvals plus RoHS conformity, covering the compliance paperwork for most industrial and commercial installations. ## IP67 sealed — washdown and outdoor field wiring Rated IP67, the zinc diecast nickel-plated enclosure and M12 x 1 thread seal keep moisture and dust out of the connection point — suitable for food-and-bev washdown zones or outdoor conveyor lines. The angled cable outlet (3.5–6 mm inlet diameter) lets the cable exit close to the panel surface, reducing strain on the connector in tight routing. ## 4 A per pin at 250 V — field device power and signal Each of the 4 poles carries up to 4 A at 250 V maximum, with a 2.5 kV surge voltage rating — enough for powering small sensors or actuators and for signal-level I/O in a 24 VDC control loop. Screw terminals accept flexible conductors up to 0.75 mm², a common size for M12 field cables; the 100 mating-cycle mechanical life is typical for a field-connectable socket.","metaTitle":"Siemens 3RK1902-4CA00-4AA0 M12 Socket, 4-Pole, IP67, 4 A","metaDescription":"Siemens 3RK1902-4CA00-4AA0 M12 angled socket, 4-pole, screw terminals, 4 A per pin, 250 V, IP67.
