Wheel Type Incremental Rotary Encoder

Features

● Suitable for measuring the length or speed of
target moving successively by wheel type

● The output waveform according to measuring distance is
proportional to the unit of International Measurement type
(meter or inch)

● Power supply: 5VDC, 12-24VDC ±5%

Applications

● Various packing machine, sheet manufacturing, textile
machinery, and general industrial machinery etc.

Please read “Safety Considerations”
in the instruction manual before using.
