(*1) The values above are typical values after the calibration with our shipping test device and are not guaranteed.
(*2) The user is requested to install the magnetic drum and installation ring in the encoder within the accuracy
range specified herein. Even when the accuracy of the encoder when shipped and when installed by the user
is both within the specified range, there is a difference in the installation position. Therefore, the accuracy at
the time of our shipment may not be acquired.
(*3) It is the degree of protection when fitted with a connector.
