Rotary Encoders

Rotary Encoders

The rotary encoders of DIS Sensors enable contact-free measurement of an angular displacement from 0° to 360° without a mechanical stop. These sensors are available in two types of housing:


In the QR30 range, the sensor and magnet are mounted separately from each other. The maximum distance of 3 mm between the magnet and the sensor provides sufficient space for mechanical tolerances under extreme conditions. Various outputs are available with a 10 or 12-bit resolution.

The QR30-series is available as absolute or incremental rotary encoders. An absolute rotary encoder contains an analog output which is linear with the angle of rotation, up to 360° whereas an incremental encoder is especially suitable for rotational velocity of a shaft.


In contrast to the QR30 series, in the QR40 series of rotary encoders the magnet is built into the sensor. The QR40 also has a zero-input, which makes it possible to zero the device after installation, ensuring a non-critical mounting procedure.
