A102H incremental encoder
The A102H Photoelectric Rotary Encoder is a high-precision, large-diameter incremental encoder designed for demanding motion-control applications. With 5,000 lines on the disc in the standard version, it can produce up to 500,000 pulses per revolution, and additional configurations are available on request.
Featuring the largest shaft diameter in our rotary encoder range, the A102H is ideal for applications requiring robust mechanical integration and high-resolution angular measurement.
