Hall-effect rotary position sensors provide angle monitoring in harsh applications

Latest from TTI Europe is the Honeywell RTY Series Hall-effect rotary position sensor which competitively provides angle monitoring in harsh transportation and industrial applications. The sensors use a magnetically biased, Hall-effect integrated circuit (IC) to sense rotary movement of the actuator shaft over a set operating range. Rotation of the actuator shaft changes a magnet’s position relative to the IC. The resulting flux density change is converted to a linear output. The IC, together with conditioning and protection circuitry, and the permanent magnet, is sealed in an IP67-qualified rugged package for durability in a wide range of harsh environments. Eight operating ranges (50°, 60°, 70°, 90°, 120°, 180°, 270° and 360°) are tolerant to over-travel and allow use in most common applications. Low voltage and high voltage versions cover an input voltage range of 4.5VDC to 30VDC. Although most applications require no lever, a lever version is available. The lever may allow users to reduce the number of mechanical linkages required for their application, which may reduce the cost of the overall solution. No brackets are necessary, says the company.
