Versions are available that can provide quadrature (bi-directional) or single direction output. Both Hall Effect and Magneto-Resistive sensors are true zero-speed sensors. Magneto-Resistive sensors, because of their higher sensitivity, are better suited for sensing ferrous metal targets at substantially longer distances; up to .250" or greater. The tradeoff is that they are more susceptible to producing false pulses from inductive fields. This might make them unsuitable for applications where they will be in close proximity to large motors or generators, etc. These sensors are built on a custom basis to satisfy specific application requirements.
