Curtiss-wright NRH300DP

No-contact, Rotary Position Sensor, Varying Voltage Range of 9-30v.

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.

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 batter. The  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.
