Notes:

1. Exposure to extreme light intensity (such as from flashbulbs or spotlights) may cause permanent damage to the device.

2. CAUTION: It is advised that normal static precautions should be taken when handling the encoder in order to avoid damage and/or degradation

induced by ESD.

3. Proper operation of the encoder cannot be guaranteed if the maximum ratings are exceeded.
