    *1. When the Rotary Encoders power is turned on, an inrush current of about 9A flows. (Time: about 5μs)
    *2. The code is as follows.
    Rotary Encoders Output CoderesolutionCode No.
    BCD3600 to 359
    Gray Binary2560 to 255
    36076 to 435 (76+ grays)
    720152-871 (152+ gray)
    1,0240 to 1,023
      *3. Maximum electrical response speed is determined by the resolution and maximum response frequency.
      Maximum electrical response speed (r/min) = Maximum response frequency/resolution x 60.
      Therefore, if you Rotary Encoders it at the maximum response speed or more, the signal will not follow electrically.

        Cautions and Prohibitions of OMRON Rotary Encoders

        • This Rotary Encoders product cannot be used for directly or indirectly detecting the human body for the purpose of ensuring safety.
        • Do not use this product as a detection device for personal protection.
        • Do not use in an atmosphere or environment that exceeds the rated capacity.
          ●When reading the output code during adjustment
          , for the Rotary Encoders E6F-AB3C and E6F-AB3C-C models, wait until the LSB (output 20) has changed. ●When connecting
          , false pulses may occur when the power is turned on or off, so use subsequent models 0.1 seconds after the power is turned on and 0.1 seconds before it is turned off.
          Also, when turning on the power, turn on the encoder power first, then the load power.
