Instruction manual

*1. An inrush current of approximately 6 A will flow for approximately 0.3 ms when the power is turned ON. 
*2. The maximum electrical response speed is determined by the resolution and maximum response frequency as 
       follows:
E6H-C Specifications 2
        This means that the Rotary Encoder will not operate electrically if its speed exceeds the maximum electrical 
        response speed. 
*3. No protection is provided against water or oil. 
*4. The line driver output is a data transmission circuit compatible with RS-422A and long-distance transmission is 
       possible with a twisted-pair cable. The quality is equivalent to AM26LS31.

Caution: All units are in millimeters unless otherwise indicated.
Tolerance class IT16 applies to dimensions in this datasheet unless otherwise specified.
