Baumer IFRM 12N1702/L Proximity Sensor

The Baumer IFRM 12N1702/L proximity sensor delivers solid-state performance within a compact 12 mm cylindrical threaded housing, offering a nominal sensing distance of 4 mm for detecting metal targets with precision. The sensor operates using an NPN make function (normally open) and comes pre-wired with a robust 2-meter cable, ensuring seamless integration into control panels, production equipment, or field wiring systems without the need for connector adaptation.

Operating on a broad voltage range of 6–36 VDC, the sensor supports output currents up to 200 mA and maintains reliable switching with a 2 kHz response frequency, ideal for high-speed automation and conveyor-based systems. Equipped with short-circuit protection and reverse polarity protection, this model ensures operational safety and reduces downtime caused by wiring errors. Its status LED red indicator provides visual confirmation of switching activity, streamlining diagnostics during maintenance routines.

The rugged construction of the IFRM 12N1702/L includes a PBT sensing face and a brass nickel-plated housing, making it resistant to wear, chemicals, and vibrations in harsh industrial environments. Rated with an IP67 protection class and capable of withstanding temperatures from -25°C to +75°C, this sensor is designed for longevity and reliability. Whether you're upgrading a legacy system or building new machinery, Baumer's trusted engineering ensures the IFRM 12N1702/L performs consistently across applications.
