Honeywell’s RTY Series Hall-effect Rotary Position Sensors provide angle monitoring in harsh transportation and industrial applications at a competitive cost. These new devices provide a cost-effective rotary position sensor solution with a variety of options (e.g., sensing range, pinout, and voltage) that allow customers to choose the configuration of the sensor to meet their specific application needs.

These products 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 most 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 4.5 Vdc to 30 Vdc. Most applications require no lever, and no brackets are necessary.


  • 15 M cycle product life: Provides long life in the application
  • Solid-state Hall-effect technology: Provides non-contact operation, long service life, low torque actuation and reduces worn-out mechanisms
  • Rugged IP67-sealed package with integral connector: Allows for use in harsh environments
  • Automotive-grade EMI/EMC testing, integrated reverse polarity, and short circuit: Provides protection against installation errors and frequencies in the environment
  • Industry-standard AMP termination, 32 mm mounting pitch, North American and European pinout styles, and compact package: Provide drop-in replacement
  • Eight operating ranges up to 360°: Provides flexibility in multiple applications, allowing OEMs the range of travel needed for the application


  • Transportation:
    • Position and movement detection of pedals, throttles, gear shift, levers, steering, linkages, and hitches (trucks, buses, off-road vehicles,
    • industrial/construction/agricultural vehicles and equipment, cranes)
    • Suspension displacement/kneeling (buses, trucks)
    • Tilt/trim position (boat engines, tilling equipment)
  • Industrial:
    • Valve control
    • HVAC damper control
    • Irrigation pivot control
