NSK motor encoder units use a compact and robust sensor that produces an incremental encoder signal. The sensor is accurate down to zero r/min. An integrated active circuit (requiring an external voltage supply) in the sensor body contains two Hall effect cells that produce an output signal consisting of two square waves.

The signals can be interpreted by motor controllers in different ways:

The direction of rotation can be determined from the phase shift, when the rising edge of a signal first appears.
Slow speeds can be determined by measuring the time between two electrical events, events being the rising and falling edge on either square wave.
High speeds can be measured by counting the number of electrical events within a given time period.

The two square waves are 90° out of phase with each other. This phase shift changes sign with the direction of rotation. The presence of two signals in quadrature enables a processing unit to multiply the number of angular position increments per revolution. For example, using a standard NSK sensor bearing with 64 pulses per revolution and a standard electronic interface that can detect the rising (Low/High) and falling (High/Low) times of each of the two signals, it is possible to obtain 256 electrical events per revolution, which translates to an angular resolution of 1,4°.
