Rotary Position Sensor From Cherry Is Completely Non-Contacting

Prairie, WI - Cherry's new AN9 series dual-output rotary position
sensor is electrically and physically non-contacting, making it
ideal for applications where high reliability and uncertain physical
tolerances are involved. Its dual output design offers an additional
dimension of reliability, allowing a connected controller to diagnose
potential problems in the sensing system.
sensor output is programmable, but it is available in standard
output ranges from 0-45 degrees to 0-360 degrees. Its non-contacting
nature means that unlimited rotations are possible. Designed for
automotive and off-road environments, the sensor is also sealed
to IP68 for resistance to water immersion.
AN9 eliminates the most common cause of rotary position sensor
performance problems by removing the mechanical interface between
rotating shaft and sensor. In Cherry's unique design, a rotating
member mates to a separate magnetic actuator. This means that
mis-alignment or changes in the shaft position will not physically
impact the sensor. While potentiometric sensors may suffer from
wear or dither and traditional non-contacting sensors may experience
binding or jamming, the Cherry AN9 sensor is vulnerable to none
of these potential failure modes.
Hall-effect-based AN9 offers a 5vdc ratiometric output. It is
suitable for a wide range of applications, including: steering
wheel position sensor, shift-by-wire sensor, variable valve timing
position sensor, and pedal position sensor for braking and acceleration.
