Rotary encoders are widely used in modern typical applications: CNC machine tools, printing equipment, packaging machinery, conveyors, elevators, robots, wind power, cranes. CNC machine tools using a rotary encoder precise control of the tool and the table; elevators using a rotary encoder to confirm the car floor; conveyor belt using a rotary encoder to monitor the speed and distance of an object moving on the conveyor; robot uses a rotary encoder position and drive monitoring tool axis movement; rotary encoder controls the position of the crane, the crane measuring speed, overspeed protection; wind power using a rotary encoder control blade angle and wind speed; packaging machinery using a rotary encoder measures the length of the target, calculate the number of packaging film ; printing equipment using a rotary encoder to calculate the length of the paper, and confirm the cutting position, and so this series described rotary encoder in a wide range of modern industry, rotary encoders of various dimensions, installation specifications are not now, according to user demand can be customized, long-term stocking conventional size. Domestic rotary encoder affordable. Rotary encoder incremental encoder, absolute encoder, incremental encoder with solid shaft, hollow shaft (semi-hollow shaft) encoder, absolute encoder with solid shaft, hollow shaft (semi-hollow shaft) encoder, rotary absolute encoder is divided into single-turn absolute encoder, multi-turn absolute encoder.
