Pneumatic Sensor

Sensors are used to provide position feedback to control systems in automated machinery and equipment. Pneumatic cylinders use sensors to detect the linear position of the piston for applications where position feedback is crucial. The most common type of sensor used for pneumatic cylinders are magnetic proximity sensors, which detect the magnetic field of a magnet integrated in the cylinder piston. The sensor is mounted onto the pneumatic cylinder’s body and will indicate “ON” or “OFF” based on proximity to the magnet. Depending on the application, various different magnetic proximity sensor technologies can be used to maximize performance, space, and reliability. Figure 1 shows examples of different pneumatic cylinder proximity sensors.
