Non-Contacting Chassis Level Sensor
Introduction
Bourns® Chassis Level Sensor is based on Anisotropic Magneto-resistance (AMR) sensor technology. The sensor arm or lever is
attached to a magnet that is suspended above the MR sensor chip. The angular position of the sensor arm is measured and an
output signal that is proportional to the angular orientation is generated. The output characteristic can be programmed to the customer
specification. The output of the sensor can be programmed to be symmetric to allow the sensor to be mounted in all four suspension
locations when used as a chassis level sensor or other applications.
