The Festo SME-8F-DS-24V-K0,3-M8D is a magnetic reed proximity switch in the SME-8F series, built for cylinder position sensing in pneumatic actuators. IP65 rating means the housing and M8 3-pin connector withstand washdown spray — suitable for packaging, food-and-bev, or automotive assembly lines where coolant or cleaning fluids hit the sensor body.
Rated supply voltage is 30 V, with a normally open switching output rated 0.5 A continuous and 10 W DC max. That 10 W ceiling governs inductive loads — a solenoid valve or small relay coil must stay under the product of voltage and current at the switching point. Dimensions are 5 x 6 x 33 mm, fitting the standard T-slot on Festo cylinders. The M8 3-pin connector mates with standard M8 cordsets; no rewiring needed if the existing panel uses the same pinout.
