SMART Position Sensor, Rotary Configuration DESCRIPTION Honeywells SMART Position Sensors are some of the most Honeywell uses a patented combination of an ASIC and an durable, adaptable, and lightweight absolute position sensors array of MR sensors to accurately and reliably determine the available in the industry, enabling highly accurate motion position of a magnet collar attached to a rotating object so that control and improving operation efficiency and safety. the objects position can be determined or controlled. The output and the MR sensor sequence determine the nearest Why is the SMART Position Sensor smart SMART means pair of MR sensors to the center of the magnet location. The that this is a sensor that can essentially think for itself. With the output of these two MR sensors is then used to determine the SMART position technology, Honeywell has utilized MR position of the magnet between them. (magnetoresistive) technology through the ASIC (Application- Specific Integrated Circuit) at a level never before The SMART Position Sensor, Rotary Configuration, fits on a accomplished. The rotary configuration joins Honeywells 25,4 mm 1 in shaft. A mounting tool fixture (purchased SMART Position Sensor family of proven linear and arc separately) provides repeatable installation. configurations. The SMART Position Sensor, Rotary Configuration, is a non- contacting sensing solution for absolute position sensing with enhanced accuracy. It senses the position of a magnet relative to the sensor in a range of 0 to 360.
