Features ■ Non-contacting sensor technology ■ Programmable output characteristic Non-Contacting Angle Sensor Introduction Bourns® Non-contacting Angle Sensor is based on a two-axis Hall sensor element. The rotor is connected to a magnet that is mounted above the sensor ASIC-chip. Its angular position is measured and an output signal proportional to the rotor orientation is generated. The output characteristic can be programmed to meet specific customer specification.

Customers should verify actual device performance in their specific applications. The output of the sensor is programmable to offer an analog or PWM output, selectively. Furthermore, it can be programmed for offset, gain and clamping to meet any rotary position sensor output transfer characteristic. The angular range is adaptable from 20 ° to 360 °.
