Baumer IFRM 05N17A1/PL Proximity Sensor

The Baumer IFRM 05N17A1/PL, part no. 11082476, stands out for its precision, durability, and efficiency in detecting metallic objects within automation processes. Built with a cylindrical threaded stainless steel housing and an LCP sensing face, it is engineered for long-term reliability, even in high-vibration or dusty environments. Its compact 5 mm diameter and 25 mm housing length allow seamless integration into machine structures and panel enclosures where space is at a premium.

Technically, the sensor operates on a 6–30 VDC power supply and consumes just 12 mA in no-load conditions, making it both energy-efficient and compatible with standard control circuits. It supports an NPN make (NO) output circuit capable of handling up to 100 mA, suitable for direct connection to PLC inputs. The nominal sensing distance is 1.6 mm, supported by a fast 3 kHz switching frequency, which ensures precise detection of small or fast-moving parts. The voltage drop is maintained below 2 VDC to reduce signal loss. It comes with a 2-meter cable connection for flexible wiring and an integrated red LED output indicator for quick status checks during commissioning.

With an operating temperature range of -25 to +75°C and IP67 protection rating, the sensor remains functional in demanding industrial environments, including those exposed to dust, oil, and fluctuating temperatures. Backed by Baumer's quality assurance, the IFRM 05N17A1/PL is a trusted choice for control engineers looking for stable performance, compact design, and reduced maintenance. The Baumer IFRM 05N17A1/PL is widely used in compact automation systems where precise detection and small form factor are critical. Its flush mounting design and threaded housing make it suitable for embedded applications like robotic tooling, jig positioning, and compact machinery panels. Engineers often choose this model in assembly lines for detecting metal stoppers, slider presence, or guiding mechanical arms.

Its 1.6 mm sensing distance ensures accurate proximity sensing for small metal objects, while the 3 kHz switching frequency handles rapid detection cycles required in automated testing or sorting systems. The LCP sensing face adds mechanical strength and resistance to environmental stress, making it ideal for machines that experience temperature changes, light moisture, or frequent cleaning.

This sensor is also preferred in OEM designs for electronics manufacturing, small part conveyors, and machine tool referencing. The IP67 protection class ensures safe operation in dusty workshops or washdown areas. With Baumer’s reputation and consistent field reliability, the IFRM 05N17A1/PL supports both new installations and MRO replacements, delivering dependable performance in critical sensing roles.
