Baumer IFRM 18P1701 Inductive Proximity Sensor

Baumer IFRM 18P1701/S35L is an 18 mm‑diameter inductive proximity sensor housed in brass with a nickel‑plated finish and a PBT sensing face, designed for rugged industrial environments. It delivers a PNP normally open (NO) output with a nominal sensing distance of 8 mm, suitable for detecting metallic targets within that range. The device operates from a 6–36 V DC supply, draws about 10 mA no load, and can source or sink up to 200 mA with a load voltage drop under 3 V. An integrated four‑LED indicator provides clear status signals, while built‑in reverse polarity and short‑circuit protection help improve reliability in demanding lines. The sensor supports a switching frequency up to 500 Hz and uses an M8 connector for the electrical interface; its body is 18 mm in diameter with a 50 mm housing length. It is rated IP67 and operates from −25 °C to +75 °C, enabling use in wet or dusty environments. Typical applications include machine automation tasks such as end‑of‑travel and metal‑target presence sensing on conveyors or tooling, where an 8 mm sensing range is sufficient. DoC/CoC certificates are available for this model as documented by Baumer.
