What to be noted when selecting an encoder！

It should be noted parameters in three areas:
(1) Mechanical dimensions, including positioning spigot, shaft, mounting holes; cable and outlet; installation space volume; environment protection level meets the requirements.
(2) resolution, which work when the encoder output pulses per turn, whether to meet the design requirements for the use of precision.
(3) 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-term driver output. Its output should and its control system interface circuit to match.
