Festo SME-8M-DS-24V-K-2,5-OE Proximity Sensor Reed 500mA 2.5m Cable

Overview
The Festo SME-8M-DS-24V-K-2,5-OE (part number 543862) is a magnetic reed proximity sensor from the SME-8M series, designed for non-contact piston position detection in T‑slot pneumatic cylinders and grippers. This 3‑wire sensor features a bipolar, Normally Open (NO) reed contact output, a wide operating voltage range of 5 to 30 V AC/DC, and a 2.5 m PUR cable with open end leads, providing maximum flexibility for installation in automation systems.

The sensor is engineered for reliable performance in dynamic applications, with a proven cable durability of over 5 million cycles in energy chains at a 75 mm bend radius, making it ideal for use with industrial robots and pick‑and‑place systems. The yellow LED provides clear switching status indication, and the sensor can be inserted into the T‑slot from above or lengthwise, then secured with a screw clamp, ensuring a flush fit without protruding beyond the cylinder profile.

With an IP65/IP68 protection rating, the sensor is dust‑tight and protected against water jets and temporary immersion, suitable for harsh industrial environments including washdown areas and outdoor installations. The housing is made of high‑alloy stainless steel and PA, offering excellent corrosion resistance and durability. The sensor operates reliably from -40 °C to +70 °C, with an additional temperature range for moving cables of -5 °C to +70 °C. It is RoHS compliant, oil‑resistant, and carries global safety certifications including CE, c‑UL‑us (OL), RCM, and CCC.
