Absolute Optical Shaft Rotary Encoder • Built-in mechanical gear module (Mechanical multi-turn) • Built-in electronic memory chip (Electronic multi-turn)） • Multiple electrical interfaces, uniform mechanical dimensions • Simple installation，Large mechanical tolerance

Optical theory absolute encoders are widely applied to high resolution required machines. On the disc of absolute encoder, there are many transparent and opaque light channels. The absolute encoder outputs a set of binary code or gray code through reading the transparent and opaque lines on the disc. The mechanical position of the lines on the disc decide the accurate position information. This optical absolute encoder will not be interfered if power is off.
