　　With a rotary encoder, incremental rotary encoder acclaimed Why? Incremental rotary encoders Absolute rotary encoders comparing what advantage? Pay attention to what in the choice of incremental rotary encoders it? Look below to share.
　　Incremental rotary encoder accepts its conversion tube angle encoder timing and phase relationships through internal two photosensitive give the angle encoder angular displacement increased (positive direction) or decrease (negative direction). Especially after joining the digital circuit is a single chip, incremental rotary encoder measures the angle and angular velocity measurements comparing absolute rotary encoder is more cheap and easy advantage.
　　Therefore, the incremental rotary encoder is widely used, but we should be concerned about before incremental rotary encoder selection under the following three problems:
　　1. mechanical installation dimensions, including positioning spigot, shaft, mounting holes; cable and outlet; installation space volume; environment protection level meets the requirements;
　　2. Resolution, that when the number of encoder output pulses per turn, whether to meet the design requirements for the use of precision; 　　3. The electrical interface, the encoder output common push-pull output (F-type HTL format), output voltage (E), open collector (C, C is the common type NPN output tube, C2 PNP type tube output), long drive output. Its output should and its control system interface circuit to match.
