Air gap is one of the vital requirements to this sensor to operate normally and to measure the
target gear’s speed and direction accurately. It varies from target to target, contact Parker
Engineering for optimum airgap before installing the sensor in the application. Failing to mount
the sensor within the optimized airgap range, would cause incorrect output information and may
not give output at all.
Always prevent the sensor making physical contact with the rotating target as will lead to
damage of the sensor and/or damage to the surrounding environment.
Sensor orientation is as important to the operation. If the mounting orientation is not measured
for a specific target, application could see signal jitter which causes inaccurate speed
measurements.
The perfect optimized orientation would be the Hall elements inside the sensor should be 90
degrees to the target gear’s tooth angle.
Due to manufacturing tolerances, evaluation by the OEM is required to verify the output signal is
of acceptable quality after the sensor is properly mounted.
