Single position sensors

Optical single position sensors measure a single-point on the stroke of a hydraulic cylinder. They are integrated, difficult to tamper with and insensitive to electro-magnetic fields. These optical sensors are designed for agricultural and earthmoving machinery and are used in harsh environments.

Main applications: measurement of the centre or end of stroke on steering cylinders, stabilisers and telescopic cylinders.
