The automatic door encoder consists of a photoelectric code disc with a shaft in the center, on which there are circular and dark engraved lines, and is read by photoelectric transmitter and receiver devices to obtain four groups of sine wave signals combined into A, B, C, D, Each sine wave has a phase difference of 90 degrees (relative to a cycle of 360 degrees). The C and D signals are reversed and superimposed on the A and B phases to enhance the stable signal; in addition, a Z-phase pulse is output per revolution. Represents the zero reference position. Since the phases A and B are different by 90 degrees, the encoder's forward and reverse rotation can be judged by comparing whether the A phase is the first or the B phase. The zero reference position of the encoder can be obtained through the zero pulse.

The materials of automatic door encoder code discs are glass, metal, plastic. The glass code disc is made of thin engraved lines deposited on the glass, which has good thermal stability and high precision. The metal code disc is directly engraved with and impassable lines, which is not easy But because the metal has a certain thickness, the accuracy is limited, and its thermal stability is an order of magnitude worse than that of glass. The plastic code disc is economical, and its cost is low, but accuracy, thermal stability, and life are required. Worse.

Resolution-The number of open or dark engraved lines provided by the automatic door encoder per 360 degree rotation is called resolution, also called resolution indexing, or directly called the number of lines, generally 5 to 10,000 lines per revolution.
