New Feature: If the power always keeps on, the single-turn encoder can be used as an electronic multi-turn encoder (but this function does not have the power-off memory feature), the total turns can be counted up to one million turns or more. Now that it has the measuring speed function, which is easy for users to calculate. When it is used as a single turn absolute encoder, any position within the measuring range is unique, even if there is interference or movement after power break, the position information will not be lost.
