Festo SMEO-1-LED-24-B Proximity Sensor, Magnetic Reed, 12-27

The Festo SMEO-1-LED-24-B is a magnetic reed proximity sensor — a sealed-contact switch that closes in the presence of a magnetic field, typically from a cylinder piston magnet. It is designed for end-of-stroke detection on pneumatic actuators in industrial automation lines. Rated for 12 … 27 V DC, it switches loads up to 1 A and 27 W, making it suitable for direct input to a PLC or relay interface without an intermediate amplifier. The 0.5 ms switch-on time holds takt time on fast-cycling stations — no jitter that would stall a pick-and-place or clamp sequence. IP67 rating means the sensor body and cable entry withstand washdown and coolant splash — common on machining cells and food-grade packaging lines. The zinc die-cast housing handles mechanical abuse in tight fixture zones.
