The Festo SMT-8-PS-S-LED-24-B is a PNP normally-open proximity sensor designed to detect piston position in cylinders with an integrated T-slot groove. It operates on 10-30 V DC and switches up to 500 mA, making it a standard choice for end-of-stroke sensing on pneumatic actuators.
Rated IP65/IP67, the sensor body and cable entry handle washdown environments — suitable for food-and-beverage or packaging lines where hosing down the machine is routine. The 500 mA switching current covers direct drive of small solenoids or indicator lamps without a relay interposer.
