Baumer Group IFRM 08N3703 S35L Proximity Switch

The Baumer IFRM 08N3703/S35L is a compact, rectangular inductive proximity switch designed for flush-mount installations in demanding environments. It features a nominal sensing distance (Sn) of 2 mm with hysteresis between 3 and 20% of Sr, and it operates from a 6–36 VDC supply, drawing up to 12 mA no-load. The device uses a NPN output configured as a normally closed (NC) contact, with a voltage drop of less than 2 VDC and an output current rating up to 200 mA, along with short-circuit and reverse-polarity protection. The sensing face is made of PBT, housed in a nickel-plated brass body, sized at 8 mm with a 49 mm housing length, and it connects via an M8 connector for easy integration. It is designed for flush installation (Einbauart Bündig) and operates in ambient temperatures from -25 to +75 °C, with an IP67 enclosure rating for protection against dust and water ingress. This specific S35L variant encompasses the core IFRM family characteristics, offering reliable, metal-target sensing in compact automation and robotics applications where a 2 mm range and robust environmental sealing are essential.
