It can be used as a linear encoder or off-axis rotary encoder and unlike optical encoders, does not require a light source and is suited for optical imaging.

altSpecifications include a repeatability of 2 micrometers, a supply voltage of 3 to 6 Vdc, and current of 21 mA. The sensor provides a direct digital output using a standard I2C protocol. It is insensitive to shock, vibration, and particulates.
