The Siemens 3RK1902-2DA00 is a field-attachable PROFINET connector — 4-pole, M12 D-coded, with a shielded cable outlet and IP67 sealing. It terminates the PROFINET cable at the device end where the environment demands washdown or dust ingress protection, not a control-cabinet patch panel. Rated at 250 V and 4 A per pin, it handles the PROFINET power-over-conductor (PoE/PoDL) and signal pairs within the standard M12 D-coded footprint. The D-coding ensures it mates only with PROFINET-typed sockets — no accidental cross-plugging with A-coded sensor connectors. The zinc diecast, nickel-plated enclosure and gold-plated brass contacts give it the corrosion resistance needed in food, beverage, or chemical washdown zones. The angled cable outlet with pressure-screw strain relief accepts 6–8 mm cable diameters and flexible conductors up to 0.75 mm².
Panel integration note: The 43 × 54 × 20 mm (W × H × D) body fits into a standard M12 panel-mount cutout or cable gland plate. The screw terminals accept 0.75 mm² flexible conductor max — strip length and ferrule size follow the manufacturer's torque spec. The mechanical mating life is 100 cycles; plan for replacement on high-frequency disconnect points.
