1-1. Introduction
The SR118 series are linear magnescale units with the
scale detector built into an extremely small housing. The
cross sectional area of the unit in the sliding direction is
only 8.2
×
12.7 mm (0.322
×
0.5 in) including the mounting
head and slider. This allows the unit to be mounted on
compact stages, microscopes, precision actuators and
other objects which have extremely limited mounting
space.
1-2. Major Features
Compact scale unit
•
Compact cross sectional shape
•
Short total length
High precision
The following precisions can be obtained depending on the
effective length.
•
When the effective length is 15 (0.591) to 60 (2.36) mm (in)
: 4 µm
•
When the effective length is 100 (3.93) to 160 (6.30) mm (in)
: 5 µm
•
When the effective length is 210 (8.27) to 260 (10.24) mm (in) : 6 µm
Note
The above precision assurances are based on a traceability
system. (Measuring temperature)
Easy installation
The scale unit is easily mounted with four screws.
Note
The allowable parallelism for the mounted surface is 0.1 mm
(0.004 in) or less.
Lightweight
The SR118-015 (effective length 15 mm [0.59 in]) achieves
the lightest weight possible of only 40 g (0.088 lb).
