GEL 2449 MiniCODER with

SINCOS or DIGITAL output

The measuring system comprises the GEL 2449 MiniCODER sensor element and a precision target wheel for attachment to shafts. Suitable tooth-wheel modules are 0.4 or 1.0 mm. Precision target wheels can be ordered separately. The MiniCODER contactlessly scans the precision target wheel using magneto resistive sensors and acquires the direction of rotation, rotational speed and position of the axis.

The configurable MiniCODER records the minimum temperature, maximum temperature and rotational speed histogram; it can be calibrated automatically using the testing and programming unit

The sensor / tooth-wheel combination has been implemented on applications up to 70,000rpm and the electronics comply with the “safety integrated” standard for numerical control applications.
