1-1. Introduction

The SR127, SR128 and GB-A series of linear scales are
semi-modular types that incorporate the detector inside the
scale, and the relative positions of their scale and head are
adjusted and secured using a slider holder.
The GB-A series includes an electrically adjusted
connection cable (CH01 series), allowing it to be used as is
with Sony Precision Technology display units (LG10, LH51/
52, LH61/62, LY51/52 series, etc.)
Note
Electrical adjustment is not necessary when the serial No.
on the scale side matches the combination No. on the
connection cable side.
The SR127/SR128 series can be used with Sony Precision
Technology display units by connecting an optional
connection cable (CH series). The SR127/SR128 series
can also be used with Sony Precision Technology detectors
by connecting an optional connection cable (CE series).
Note
In these cases, electrical adjustment (PM signal
adjustment) is required. However, when the scale unit and
display unit connection cable (CH series) are ordered
together, they are shipped in the adjusted condition. Like
the GB-A series, the scale and cable should be connected
so that the serial No. on the scale side matches the
combination No. on the connection cable side.

When extending the SR127/SR128 series cable length, use
an extension cable suited to the used optional connection
cable.
When extending the GB-A series cable length, use an
optional extension cable (CE10 series).
Note
The maximum total cable length is 30 m.
