Penny & Giles • Non-contact, Hall-effect technology • Wear free - unlimited mechanical life • Simple mounting, low-profile design • Dual redundant outputs • Fail-safe outputs • Flying leads The NRH305DR is a non-contact, Rotary Position Sensor that offers the optimal combination of performance, safety and cost. The sensor utilises proven Hall-effect, sensing technology in a low-profile (8mm) housing with separate magnet for true non-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. Outputs are ratiometric with respect to a regulated 5Vdc supply voltage. The maximum air gap between magnet and sensor is 8mm, 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. To enhance system performance, the NRH305DR has a second, redundant output that can be used for error checking in safety-critical applications. The versatile, factory-programmable electronics can be easily set to one of two analog voltage output ranges or one of three PWM frequencies. In addition, the polarities of each of the analog outputs can be independently set. On-board diagnostic functions ensure the outputs are put into safe, pre-defined states should an internal sensor error be detected. The sealed design offers exceptional levels of performance with respect to water and dust, shock, vibration and temperature, meaning the sensor is ideal for use in hostile, on- and off-highway vehicle environments. Connection to the sensor is with simple flying leads for customer termination.

Per the table above, other air gaps are possible but some specifications may vary. Please consult Curtiss-Wright for further details. This product includes diagnostic features that will put the sensor into a safe operating mode If the unit is operated when the magnet is absent or outside of the recommended air gap (the output will default to <0.1Vdc or a 0% PWM duty cycle).
