Rated for 200 V DC or 230 V AC, it switches up to 1 A with a 40 W contact rating, so it handles pilot-duty loads like PLC inputs, relay coils, or indicator lamps in pneumatic actuator feedback circuits. IP67 enclosure and protection class II mean the sensor body is sealed against washdown and dust ingress — no earth connection required, which simplifies wiring in wet or washdown zones on packaging or food-processing lines. The 2.5 m PVC cable gives enough reach to a junction box or terminal strip without a splice.","metaTitle":"Festo SME-1-B Proximity Sensor, Magnetic Reed, 500 Hz, 40 W","metaDescription":"Festo SME-1-B magnetic reed proximity sensor, 200 V DC / 230 V AC, 1 A output, 40 W contact rating, IP67, normally open, PVC cable 2.5 m.
