Optical Absolute Position Sensors
Optical absolute position sensors measure the stroke of a hydraulic cylinder. They measure the stroke with high accuracy of less than 0.1mm, are integrated and do not involve invasive mechanical work such as drilling into the piston rod. The main applications of these sensors are continuous measurement on steering cylinders, suspensions, and stabilisers.

Operation and Applications
Optical absolute position sensors are designed for the mobility sector and specifically for agricultural and earthmoving machinery working in harsh environments.
Unlike single position sensors, absolute position sensors measure the stroke of a hydraulic cylinder, making it possible to continuously monitor the exact position of the piston rod within the cylinder.
