Balluff BMF 305K-PS-C-2-S49-00,2 Magnetic Field Sensor

Balluff BMF 305K-PS-C-2-S49-00,2 is a compact magnetic field sensor designed for slot- and cylinder-based position sensing, packaged in a 33.5 × 10.5 × 6.5 mm LCP housing with a PU sensing face and an IP67 protection rating. It features a 3‑wire DC supply with a PNP normally‑open output, powered by 10–30 V DC (nominal 24 V) and capable of a maximum 200 mA load current with a voltage drop around 2.5 V. The sensing element detects magnetic fields with a rated operating field strength of 1.2 kA/m and an assured operating field strength of 2 kA/m, offering 1.0% repeatability and 45% hysteresis relative to the nominal field. Wiring is via a 3‑pin S49/M8 connector, and the device includes short‑circuit protection and reverse polarity protection, conforming to IEC 60947‑5‑2 (DIN EN 60947‑5‑2). Operating temperature spans -25 to +70°C, with a switching point drift of about 0.3%/°C. Switch‑on and switch‑off delays are each 0.05 ms, enabling fast, contactless position confirmation. Applications typically include cylinder or actuator assemblies requiring reliable, compact magnetic field sensing in harsh environments, where a durable, non‑contact NO output sensor with robust protection and quick response is essential.
