The IFRM 12P3701/S14L from Baumer is a compact, high-precision proximity sensor designed to meet the demanding requirements of factory automation and OEM machinery. Built with a 12 mm cylindrical threaded housing and a flush mounting design, this sensor is perfect for close-proximity applications, offering a reliable sensing range of 4 mm. The PNP break function (normally closed) output ensures compatibility with fail-safe PLC input configurations and is especially useful in safety-critical detection scenarios.
Operating on a wide voltage supply range of 6β36 VDC, the sensor supports up to 200 mA output current, allowing integration with relays, control units, and digital input blocks. With a switching frequency of 2 kHz, this model handles fast-moving automation cycles without signal loss. An integrated 3-port red LED indicator offers quick visual diagnostics, improving commissioning and reducing maintenance time. The sensor includes robust short-circuit protection and reverse polarity protection to safeguard control circuits in the event of wiring errors.
Housed in brass nickel-plated material with a rugged PBT sensing face, the Baumer IFRM 12P3701/S14L withstands mechanical stress, chemical exposure, and industrial vibration. Its M12 connector ensures rapid installation, while the IP67 protection rating guarantees reliable operation in dusty and wet environments. With a temperature tolerance of -25Β°C to +75Β°C, this sensor delivers dependable performance in challenging production zones.
