MULTI-CHANNEL MAGNETIC SENSOR DEVICE

Abstract:

Methods and systems for a rotary contactless potentiometer device, which includes one or more sensors, such as a Hall Effect sensor. The sensors are mounted on one or more substrates, such as a printed circuit board (PCB). In examples, each sensor channel is electrically isolated on the substrate. The sensors are arranged within range of a magnetic field, such as from a magnet rotatable about a shaft. The potentiometer device is housed in a frame to reduce stray magnetic interference.
