Sensors provide direct analog output on pneumatic cylinders

December 1, 2008

The new compact magnetic field sensor provides a direct analog output for determining the position of a piston magnet on all types of pneumatic cylinders, delivering greater accuracy than indirect analog monitoring with potentiometers or linear position systems, according to the manufacturer. The sensor detects the position of a piston on standard pneumatic cylinders by utilizing a series of Hall elements, which sense the piston magnet and send a signal back to the processor. Users can reverse the sensor’s analog output slope by rotating the sensor 180 degrees. This feature eliminates the need for two separate sensors and helps streamline the production process. The sensor is equipped with a robust mounting system to ensure stability during operation. Two pre-fixed tips are located on each end of the sensor to help seat the sensor in the T-groove until the screw is tightened. The sensors include a broad range of accessories, from precision mounting to wire-strain relief products, to facilitate installation in all T-groove pneumatic cylinders.
