position sensors are the universally usable position transmitters.
Furthermore, more complex or programmable solutions are available as position sensors, which are optimized for certain actuators.
Encoders are another product segment. These are mainly required for servo-pneumatics and are used with certain servo-pneumatic regulators.
Position transmitters are used for analog feedback of the piston movement in a certain detection range in applications such as press-fitting, screwing, clamping, go/no-go detection etc.They are able to detect the magnetic field of the piston magnet over a wide range and evaluate it with high repeat position accuracy. The information is provided as a standardized 0-10 V, 4-20 mA analog signal or via IO-Link. In addition, the devices offer programming options for pre-evaluation of the signal information directly in the transmitter.
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 position sensors safely and reliably for its own actuators.
