SICK IMF12-04BPSNC0S Background Suppression Photoelectric Sensor

The SICK IMF12-04BPSNC0S is a compact cylindrical inductive proximity sensor with background suppression (BPS), offering a 4 mm sensing range (Sn) and a 3.24 mm safe sensing range (Sa) for stable metal detection in tight spaces. It provides a PNP normally open (NO) 3‑wire output on a male M12, 4‑pin connector and operates from 10 to 30 V DC with a maximum current of 200 mA, including short‑circuit and power‑up pulse protection. The device uses a V4A stainless steel housing (AISI 316L compatibility) with a flush installation design and a plastic (LCP) sensing face; its overall housing length is 65 mm, thread length 48 mm, and it is rated IP68/IP69K, suitable for washdown and harsh environments. IO-Link V1.0 on COM2 (38.4 kBaud) supports 1‑byte process data, and the unit has an MTTF of about 1,971 years, along with robust protections and two V4A stainless steel mounting nuts included.
