SGMBH Dimensions in inches (mm)
(1) 17 Bit Incremental/Absolute Encoder
Drawings that provide SGMBH servomotor dimensions are shown below.
Note:
1.
Dimensions are the same when using either incremental or absolute encoders.
2.
Tolerances on the dimensions of flange type LB, of shaft extensions S, and of keyway width and depth are based on JIS (Japanese Industrial Standard)
B0401 “Limits and Fits for Engineering.”
