Baumer IFRM 05N35A3/S35L Proximity Sensor

The IFRM 05N35A3/S35L from Baumer is a precision inductive sensor featuring a flush-mounted cylindrical design with a compact 5 mm diameter and an extended 36 mm housing length. It provides a nominal sensing distance of 1 mm, optimized for reliable detection of metal objects in tight installation spaces. With a switching frequency of 5 kHz, this sensor delivers high-speed detection suitable for modern automation lines. Its NPN break function (NC) output can handle currents up to 200 mA, ensuring solid-state reliability across industrial circuits. The unit operates efficiently within a 6–30 VDC supply range and consumes just 12 mA at no load, making it energy-efficient. The sensor’s robust stainless steel housing resists corrosion and impact, while the LCP sensing face ensures long-term durability in chemically exposed or high-vibration environments. A reliable M8 connector and a 3-port red LED indicator simplify installation and diagnostics. Rated IP67, the sensor can operate between -25°C and +75°C, making it dependable across a range of challenging industrial conditions.

The Baumer IFRM 05N35A3/S35L is ideal for automated part positioning, metal detection in tool changers, and feedback sensing in CNC machinery. It’s widely used in compact assembly lines, robotic arms, and electronic component feeders where precision is essential but space is limited. In pharmaceutical and food-grade equipment, the stainless steel housing and IP67 rating support hygienic design standards. The sensor’s fast switching capability ensures accurate performance even in high-speed applications such as bottle filling machines or conveyor-based inspection systems. With its compact form factor and rugged connector, it can be retrofitted easily into older machinery or embedded into modern modular automation systems. Maintenance engineers value its durability, while OEMs prefer the ease of integration and dependable signal stability in 24/7 production environments.
