Selection Guide

Proximity sensors

Proximity sensors are used for binary feedback of the piston position of pneumatic actuators. They are sensors that detect the magnetic field of the piston magnet via a magnetic field or reed contact.
They are mounted at the desired switching position in the T-slot or circumferential slot of the cylinder and output a standardized 24 V switching signal when the piston magnetic field is detected.
The range of switches covers all standard applications and also offers solutions for special industrial segments.
Piston magnetic field strength and sensor slot geometry are not standardized in the market. Both can be freely selected by any cylinder manufacturer.
Festo develops both, cylinders and cylinder sensors, and can therefore design the cylinder switches safely and reliably for its own actuators.
