Festo SME-8M-DS-24V-K-5,0-OE Proximity Sensor Reed 5m Cable 543863

Overview
The Festo SME-8M-DS-24V-K-5,0-OE (part number 543863) is a high‑precision magnetic reed proximity sensor from the SME-8M series, designed for reliable non‑contact position sensing in industrial automation systems. This 3‑wire sensor features a bipolar normally open (N/O) switching output and a 5‑meter open‑end PUR cable, providing maximum flexibility for installation in distributed machine layouts.

The sensor operates on a wide DC voltage range of 5…30 V and delivers a maximum output current of 500 mA, making it suitable for direct switching of small loads without an intermediate relay. The yellow LED provides clear, real‑time visual confirmation of the switching state, simplifying system diagnostics. With an IP65/IP68 protection rating, the sensor is dust‑tight and protected against water jets and temporary immersion, ensuring reliable performance in harsh industrial environments.

Engineered for dynamic applications, the sensor is suitable for use in energy chains and robotics, with a cable rated for over 5 million bending cycles at a 75 mm radius. The housing is made of high‑alloy stainless steel and PA, offering excellent corrosion resistance (CRC 2). The sensor operates reliably from -40 °C to +70 °C, making it suitable for extreme temperature environments. It is RoHS compliant, oil‑resistant, and carries global safety certifications including CE, c‑UL‑us, RCM, and UKCA.
