Ø28mm A28 Incremental Optical Encoder
The A28 optical rotary encoder is a compact 28mm incremental encoder designed for precision motion control in tight spaces. Its small diameter makes it ideal for installations where space is limited, without compromising on performance.
This encoder delivers up to 25,000 pulses per revolution (PPR), providing accurate and reliable position feedback for a wide range of automation, robotics, and industrial applications.
