1-1-1. SR138R series

The SR138R series is a linear scale with a built-in reference
point.
The relative positional relationship between the scale part and

Be sure to always use together with the CH04 connection cable
(optional).
Note
If the SR138R series and CH04 are ordered separately, electrical
adjustment needs to be made for the CH04 before usage. No
adjustment is necessary if electrical adjustment was requested
when ordering.
