Baumer Electric GmbH MHRM 12N5524 Inductive Proximity Sensor

Baumer Electric GmbH MHRM 12N5524/L/0500 is a cylindrical M12 Hall‑effect proximity sensor designed for speed sensing and non‑contact magnetic detection on rotating parts. It operates from 8 to 28 V DC and delivers a single push‑pull output; the model includes a 5 m termination cable (suffix /0500) for easy integration in compact automation layouts. The sensing distance ranges from 0.7 to 2.4 mm, making it suitable for detecting a magnet on a rotating shaft without physical contact. The device carries IP67 protection and is built for industrial environments, with the MHRM 12 family offering high switching frequency and a broad operating temperature; some configurations are rated up to 120 °C. Depending on configuration, 1‑channel versions provide a single output, while 2‑channel variants can monitor speed and, in dual‑channel configurations, direction of rotation. Common applications include shaft speed monitoring in small motors and gearboxes, encoderless speed sensing in automation lines, and other compact, non‑contact position/speed detection tasks where a compact M12 package is advantageous.
