Curtiss-Wright Introduces New Rotary Position Sensors

Aug. 27, 2015

Curtiss-Wright Corp. on Aug. 27 announced that its industrial division has launched a new family of non-contact, rotary position sensors from the legacy brand of Penny & Giles. These IP69K-rated sensors offer performance against water, dust, shock, vibration and temperature. The NRH271 and NRH272 rotary position sensors are for use by OEMs of on- and off-highway vehicles.

  • NRH271: The NRH271 is a 3-wire, single output variant with a supply current rating of less than 12.5mA.
  • NRH272: The NRH272 is a 6-wire, dual-redundant output variant with a supply current rating of less than 25mA. The dual-die sensor has two separately powered input supply and output channels for full electrical redundancy.

All variants of the NRH271 and NRH272 rotary position sensors are contained in a 9.5mm housing and use Hall-effect sensing technology. The electrical output spans of both models can be set to correspond to rotations of 20° to 360° in 1° increments. Two power supply options are available (5V and 9-30V). Factory-programmable electronics can be set to one of two analog voltage output ranges (0.5-4.5V or 0.2-4.8V) or one of three PWM frequencies.
