Siemens 3RG4070-3AG01 Inductive Proximity Sensor

Siemens 3RG4070-3AG01 is a compact, rectangular inductive proximity sensor from the SIMATIC PXI family designed to detect metal targets without contact in harsh industrial settings. This 3‑wire device provides a PNP normally open output and operates on a DC supply of 15 to 34 V; its sensing distance is 2 mm, making it suitable for close‑range position sensing on conveyors, stamping or punching machines, and other automation cells. The unit measures about 12 x 40 mm, is housed in molded plastic, and carries an IP67 protection rating for dust and water ingress, with an M12 connector for reliable field wiring. With a current draw around 200 mA under load, it delivers robust performance in environments where metal presence must be detected quickly and repeatedly. The 3RG4070-3AG01 uses three conductors and is wired for NO operation, enabling straightforward integration with standard PLC inputs and automation circuits, while its compact form factor helps fit into tight machine footprints.
