Festo 551368 SME-10M-DS-24V-E-0,3-Q-M8D – Magnetic Reed Proximity Sensor, C-Slot, M8 Plug
The Festo 551368 (type SME-10M-DS-24V-E-0,3-Q-M8D) is a magnetic reed proximity sensor for detecting piston position on pneumatic actuators. It fits into a C-slot from above and is held by a clamping screw, so it can be fitted or moved without dismantling the cylinder. The sensor works with a contacting, bipolar normally open (N/O) output on 5–30 V AC/DC. A yellow LED shows its switching status.
It comes with a short 0.3 m PUR cable and an M8x1 3-pin plug, which makes replacement quick and easy. The cable is suitable for energy chains and robot applications. With IP65 / IP68 protection and an operating range of −40 to +70 °C, it is a reliable position sensor for pneumatic cylinders, semi-rotary drives and grippers in automation and handling systems.
