The NRH300DP is a no-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 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 sensor to be powered
from a regulated 5V supply or a varying voltage in the range
of 9-30V, such as a vehicle’s battery.

To enhance system performance, the NRH300DP has a
second, redundant output that can be used for error checking
in safety-critical applications. The versatile, factoryprogrammable 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.
