Hall-effect sensors operate on the basis of the Hall effect – a physical property of semiconductors. When an electric current flows through a semiconductor and a magnetic field is present, the Hall effect generates a measurable voltage across the current flow. This voltage varies depending on the strength and direction of the magnetic field generated by the rotation of the encoder.
The advantages of the WPH Hall-effect sensor include:
The WPH is available with two housing diameters: 40 mm (WPH-M) and 60 mm (WPH). The encoder accommodates two standard shaft diameters: 6 mm (WPH-M) and 10 mm (WPH) in order to suit the specific requirements of your project. The single-turn encoder has a measuring range of up to 360° thanks to the non-contact sensor element. Flexible analogue output options from 0.5 to 4.5 V or 0 to 5 V allow you to adapt it to your project. The standard temperature range is -20 °C to +85 °C, but there are also versions with an extended operating temperature range of -40 °C to +120 °C available.
Typical applications for encoders with Hall-effect sensor elements:
Technical specifications for the rotary transducer WPH can be found in the data sheet WPH.
