From proximity switches, photoelectric switch to the rotary encoder

The location in the industrial control, close to switches, photoelectric switch application already quite mature, and useful. But, with the continuous development of industrial control, and the new requirements, in this way, it highlights the application advantages of rotary encoder:

Information: in addition to positioning, control room also can know its location;

Flexibility: positioning can be flexible adjustment in the control room;

On-site installation convenient and safe, longevity: the size of a fist, a rotary encoder can measure from several (including to dozens, hundreds of metres distance, n location, as long as the security of a rotary encoder installed solution, can avoid a lot of close to switches, photoelectric switch machinery installation on site trouble, are easy to be damaged and the problem such as high temperature, moisture. Because it is light code disc, no mechanical wear and tear, as long as the installation location accurate, it is often a long service life.

Muti_function change: in addition to positioning, can also be far eastone current location, speed conversion, for frequency converter, the application of the stepper motor is particularly important.

Economization: for more than one control station, just the cost of a rotary encoder, main installation, maintenance, and more, loss cost reduction, service life growth, its economization gradually highlight.

As mentioned above advantages, rotary encoder already more and more widely used in various industrial control occasions.
