Curtiss-Wright NRH300DP

No-contact, Rotary Position Sensor, No-Contact, Hall-Effect, Measurement Angle 20-360°, 5V or 9-30V Supply Options.

The Curtiss-Wright (Penny & Giles) NRH300DP utilizes proven Hall effect, sensing technology in a low-profile (8mm) housing with a separate magnet for true no-contact sensing.The electrical output span can be set to correspond to rotations of 20° to 360°, and the positional information is determined by the angle of the supplied magnet relative to the sensor body. The maximum air gap between magnet and sensor is 5.5mm, while concentric offsets of up to 2mm can be tolerated with minimal impact on output linearity. The magnet can be supplied in a convenient carrier, housed in a bolt, as a plug or loose.

  • No-contact, Hall-effect technology
  • Wear free – unlimited mechanical life
  • Simple mounting, low-profile design
  • Measurement angle 20-360°
  • 5V or 9-30V supply options
  • Single or dual redundant outputs
  • Analog output – 0.5-4.5V or 0.2-4.8V
  • PWM output – 244 Hz, 500Hz or 1,000 Hz
  • Fail-safe outputs
  • Sealing to IP69K
  • Flying leads

Innovative circuit design allows the NRH300DP to be powered from a regulated 5V supply or a varying voltage in the range of 9-30V, such as a vehicle’s battery.

The Curtiss-Wright NRH305DR supply is limited to a regulated 5Vdc supply only but includes connections for a second supply to separately power each of the two outputs, for additional redundancy and error checking.
