Operating principle and characteristics of absolute encoders

Absolute encoder performance is not easily affected by dust and condensation; its structure is simple and compact, no contact, long life, high and low temperature resistance, vibration resistance, fast response speed. Therefore, they are generally used in the fields of robotics, automated production lines, automatic assembly machines, elevators, textile machines, sewing machines, packaging and printing machines, CNC machine tools, plotters and goniometers. It can be used as a high-speed signal input element in PLC applications, enabling PLCs to implement closed-loop control more quickly and accurately. Absolute encoders use magnetic induction to measure the speed of an object and are non-contact speed measuring instruments. Absolute encoder code value" with the measured "position" corresponds to a unique, with "power failure memory" function, no rotational measurement of the accumulation of error, in "a cycle of "It is superior to incremental encoders in the field of measurement and control, and the range can be adjusted by adding a front reduction gearbox. Magnetoelectric speed sensor can be used for speed measurement of objects with gaps on the surface, has good anti-interference performance, multi-purpose...
