Rotary Position Sensors
Dual Output Rotary Position Sensor

DESCRIPTION

 
This sensor is designed for continuous output corresponding to the rotation angle of a magnetic actuator, typically Cherry’s AS500106. Two electrically independent outputs assure very high reliability.
Outputs have intentionally different transfer functions. This allows the connected controller to diagnose any problems in the sensing system, such as short circuits, broken wires, etc.

Features AND BENEFITS

  • Rotary position sensor with high tolerance for misalignment
  • Dual (redundant) outputs assure very high reliability
  • Non-contact rotary position sensing to full 360° rotation
  • No mechanical interface:
    - Nothing to break or wear out
    - No possibility of jamming or resistance to motion
  • Sealed design meets IP68 level water immersion per IEC 60529
  • 5VDC ratiometric outputs
  • Linear output over specific angular rotation ranges available on request
  • Performs with standard AS500106 magnetic actuator — factory programmable for use with other magnets
  • Custom programming option for rising or falling output slope with selectable offset, gain, clamp voltage
  • PWM output option available for custom applications
  • Rugged design includes EMI/ESD protection to SAE J1113 standards
  • Maximum operating temperature of 125°C

Applications

  • Rotary position sensor in electro-hydraulic system (heavy equipment control)
  • Steer wheel position (steer by wire)
  • Shifter position (shift by wire)
  • Brake pedal position (brake by wire)
