Rotational speed sensor BRDS series

magneticdigital outputstainless steel

This sensor gives two separated signals shifted which allow to detect not only the rotation speed but also the direction of a ferrous toothed wheel or reference marks. The frequencies of the digital output signals are proportional to the rotation speed starting from zero. The outputs are NPN open collector. The extremely strong construction allows the use in the most difficult conditions even with high pressures on the housing. The sensor must be aligned to the rotation axis of the wheel.
