    Tips: The advantages of rotary encoder

    1. Informatization: In addition to positioning, the control room can also know the specific location of encoder.
    2. Flexibility: Positioning can be adjusted flexibly in the control room.
    3. Installation advantage: using a rotary encoder with fist size, can measure from a few μ to tens, a few hundred meters interval, any number of stations. As long as solve the problem of safe installation for the rotary encoder, can avoid many troubles caused by the proximity switches, photoelectric switches in the field of mechanical installation, as well as problems such as being easily crashed and subjected to high temperature and water vapor. Since it is a photoelectric encoder, and there is no mechanical loss, therefore its service life is often very long provided the installation location is correct.
    4. Versatility: In addition to positioning, it can also load the current location from far away and converting speed, which is particularly important for the inverter, stepper motors and other applications.
    5. Economic: The cost for a rotary encoder is enough for getting multiple control stations, the more important thing is that the installation and maintenance fees are low as well, while the service life is increased, and its economy has gradually become apparent.
