Curtiss-Wright NRH271 & NRH272

No-Contact, Rotary Position Sensors, Hall-Effect, 20-360° Measurement Angle, Single or Dual Redundant Outputs, Analog Output, PWM Output.

The Curtiss-Wright (Product Brand: Penny & Giles) NRH271 and NRH272 family of no-contact, Rotary Position Sensors offers the optimal combination of performance, safety, and cost. All variants utilize proven Hall-effect sensing technology and are accommodated in low-profile housing with a compact footprint.

  • 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 – 244Hz, 500Hz or 1,000Hz
  • Fail-safe outputs
  • Encapsulated electronics
  • Sealing to IP67
  • AMP or Deutsch connector options
  • Flying-lead option
  • Protective cable conduit option

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 7mm, 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.
