Festo SMTO-4U-PS-K-LED-24 Proximity Sensor PNP NO 10-30V 2.5m IP67

Overview
The Festo SMTO-4U-PS-K-LED-24 (part number 152836) is a high-precision magneto-inductive proximity sensor from the SMTO-4U series, designed for reliable non-contact position sensing in industrial automation systems. This U-shaped sensor features a compact round design and a 2.5 m pre-wired PVC cable, making it ideal for end-position detection in Festo T‑slot pneumatic cylinders and grippers.

The sensor operates on a wide DC voltage range of 10‑30 V DC, has a PNP normally open (N/O) switching output, and delivers a maximum output current of 200 mA with a fast switching time of ≤5 ms, making it suitable for high‑speed applications. A yellow LED provides clear visual confirmation of the switching state.

With an IP67 degree of protection, the sensor is dust‑tight and protected against water jets, ensuring reliable operation in harsh industrial environments. The sensor can be used in any mounting position and has a temperature range of -25 °C to +70 °C (with flexible cable installation from -5 °C to +70 °C). It features integrated short‑circuit and reverse polarity protection, and is RoHS compliant, CE, UKCA, and RCM marked.
