Linear encoder (magnetic linear scale) systems

A measuring system consists of a magnetic scale and a reading head,
detecting the amount of linear position change and outputs the measured value.
- □ Magnetic detection ensures that the measurement is unaffected by dust and dirt, making it ideal for harsh environments.
- □ Complete non-contact between the reading head and the magnetic scale ensures long-term stability and frees users from maintenance.
- □ Long distance and fast response.
