Festo SME-8-S-LED-24 150857 T‑Slot Magnetic Reed Proximity Sensor

Festo SME‑8‑S‑LED‑24 is a magnetic reed proximity sensor for T‑slot pneumatic actuators, grippers, and linear drives. Its compact, slot-in design with an M8 connector and a 0.3 m PUR cable provides a flexible wiring solution for industrial automation. Equipped with a yellow LED status display and NO output operation, it delivers reliable end–position sensing in harsh conditions.

Applications:

• Pneumatic cylinder end‑position sensing

• Gripper position monitoring (e.g. in pick‑and‑place)

• T‑slot integrated drive systems

• General automated machinery requiring non‑contact magnetic position detection
