Baumer IFRM 05N37A3/PL Proximity Sensor

The IFRM 05N37A3/PL from Baumer features a flush-mountable cylindrical design with a compact 5 mm diameter and 20 mm housing length, making it suitable for embedded sensor configurations. It offers a nominal sensing distance of 1.6 mm and operates with an efficient NPN break function (NC) output capable of handling up to 200 mA. This inductive sensor functions across a 6–30 VDC voltage range, consuming only 12 mA in no-load conditions—ensuring minimal power usage in round-the-clock systems. It supports a switching frequency of 3 kHz, allowing it to react quickly to target detection in high-speed operations. The stainless steel housing and LCP sensing face provide strong resistance against oil, moisture, and vibration. Its 2-meter cable connection ensures easy integration into control panels or machinery. Equipped with a LED red output indicator and an IP67 protection rating, this sensor offers ease of monitoring and long-term reliability in challenging environments ranging from -25°C to +75°C.

The Baumer IFRM 05N37A3/PL is widely used in precision jigs, robotic automation systems, and position feedback applications where compact installation and flush mounting are required. It performs exceptionally in automated machinery, conveyor detection systems, and tool alignment setups. Its fast response time makes it well-suited for electronics assembly and pharma-grade automation, where accurate metal detection is critical. The rugged build allows it to endure vibration, chemical exposure, and temperature fluctuations, ensuring consistent sensing in both new installations and retrofit environments. The 2 m pre-wired cable simplifies routing in tight spaces and is especially valuable for OEMs designing minimalistic yet powerful control layouts.
