The Balluff BMF303K-PS-C-2-S49-00,2 is a compact Hall‑effect magnetic field sensor designed for non‑contact piston/slot sensing in cylinders. Housed in a 25.5 × 4.5 × 2.9 mm LCP body with IP67 protection, it uses a 3‑wire DC connection and a normally open PNP output, powered from 10 to 30 V DC (typical 24 V) and rated for up to 100 mA. It offers function indication, short‑circuit protection, and a rated operating field strength of 1.2 kA/m (assured 2 kA/m) with ripple up to 15% of Ub; ambient operating range is −25 to +70 °C. Connection is via cable with S49 connector, making it suitable for magnetic cylinder sensing in automated machinery.
