■ 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.

Specifications are subject to change without notice.
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 °.
