Round and round the globe, it's Honeywell. Our non-contacting approach to Hall-effect rotary position applications provides longer-life solutions that excel in harsh environments. Honeywell S&C seals the IC together with conditioning and protection circuitry and two permanent magnets in a rugged package.
How it works:
Using a magnetically biased Hall-effect integrated circuit (IC) designed to sense rotary movement of the actuator shaft, these transducers vary output voltage or current in response to changes in a magnetic field. The rotation of the shaft changes the IC's position to the magnets, and then detects the change in flux density. The output of the IC is converted to a linear output over 90 degrees of travel.
