Balluff BMF305K-PS-C-2-S4-01 Magnetic Field Sensor

The Balluff BMF305K-PS-C-2-S4-01 magnetic field sensor (BMF005C) is a cylinder‑style switch designed for detecting piston position in pneumatic cylinders across multiple slot shapes. Its compact 33.5 × 5 × 10.5 mm LCP housing houses a magnetic field sensing element and a PNP normally open output, and it uses an M12x1 male connector with a 3‑pin, A‑coded configuration. It ships with a PUR cable length of 1.5 m, and is powered from 10–30 V DC with a switching frequency up to 10,000 Hz for high‑speed automation applications. The sensor is IP67 rated for robust protection against dust and water, and operates across a temperature range of −25 to 85 °C. Mounting support is provided by the BMF 305‑HW mounting bracket for secure installation on larger actuators. This device is part of Balluff’s BMF 305K family of cylinder sensors, delivering reliable magnetic field detection in a compact form factor for universal actuator sensing needs.
