The SNDH-H Series Hall-effect Speed Sensors use a magnetically biased Hall-effect integrated circuit to accurately sense movement of ferrous metal targets. The specially designed IC (integrated circuit) and a permanent magnet are sealed in rugged, probe-type packages.
The flux density of the permanent magnet alters when approached by ferrous metal. This is detected by the Hall ICs. If the sensor is positioned at the circumference of a revolving gear wheel, for example, it detects the teeth and spaces, supplying a digital pulse output with frequency proportional to gear wheel speed.
Optimum performance is dependent upon variables that must be considered in combination: target material, geometry and speed, sensor/target gap, and environmental temperature.
