Siemens 3RG4612-0AN61 Proximity Sensor Switch

Siemens 3RG4612-0AN61 is an inductive proximity sensor switch that detects metal objects without contact. It operates on 10–30 V DC and provides a 3‑wire PNP output, with a typical current draw around 200 mA. The housing is stainless steel, it uses an M12 connection, and carries an IP67 rating for protection in harsh environments, with flush mounting capability. The sensing distance is 3 mm (SN=3MM), making it suitable for compact, metal-target sensing in automated equipment. Common applications include position sensing on conveyors, machine frames, and guarding interfaces in metalworking and packaging automation. Some listings also indicate it as manufactured in Germany.
