Rotational speed sensor HDD, MDD series

Hall effectnon-contacthigh-resolution

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. When mounting the double pulse sensors the mounting position has to be considered. Please take the minimum width of the actuating element and information regarding the assembly of the sensor from the respective data sheets. Mounting has to be accomplished in such a way that a vibration of the double pulse sensor and/or the actuating element is reliably prevented.
