magnetic rotational speed sensor / Hall effect / high-resolution / non-contact

Double pulse sensors of the type magnetic field are suitable for the
generation of rotation- or speed-proportional, phase-shifted pulse
sequences. From the order in which the pulses appear the user can
detect the direction of rotation and/or direction of motion. For these
sensors, static Hall or magneto-resistive elements can be used as
sensing elements.
The double pulse sensors described here have been optimized for the
scanning of specific racks and magnet wheels. We also manufacture
and develop an individual system solution for your specific
requirements.
Gearwheels or racks made of ferromagnetic steel (e.g. St 37) or
magnetised pole belts, bars and wheels are used as actuating
elements.
