1 Overview
This chapter describes the features of this product, names and functions of each part, and the ow of
the main tasks to use this product.
1.1 Features
The assembly type linear scale uses the glass scales as the unit of length, to detect changes in the
amount of light using light emitting elements and light receiving elements based on the grids, and to
output the amount of changes as a square wave (pulse).
This can precisely measure moving amounts of various instruments including printed board drill
punching machines, laser machines, and surface grinding machines.
This product is a slim shield-type scale that can be connected directly to a control unit. It supports a
wide range of resolutions from 0.1 μm–5 μm and delivers high-speed response of up to 120 m/min
(2000 mm/s). This scale is also equipped with the scale alarm indication function for easy mainte-
nance.
This product has the following two types and specications with di󰀨erent e󰀨ective measuring lengths.
yType for xing at multiple points with excellent vibration resistance or impact resistance
yType for xing at both ends for space-saving installation

2 Setup for Installation
This chapter describes the preliminary preparation for installing this product onto the machine main
unit.
2.1 Checking the Equipment Model
The AT211 model number is determined based on the e󰀨ective length, installation method, scale ref-
erence point, indication accuracy, resolution/minimum edge interval/response speed, direction, detec-
tor cable, and signal cable.
Make sure that your scale unit model satises desired specications.

2.2 Designing the Installation of the Scale Unit
2.2.1 Scale Main Unit Mounting Directions and Cover Preparations
When installing this product, be sure to install the cover so that cutting oil, chips, etc. do not splatter
onto the scale main unit.
Only the dust proof-rubber lips are used to protect the opening side of the scale main unit from the in-
trusion of foreign objects. Therefore, when deciding the mounting direction of the scale main unit, give
consideration to the splattering directions of the cutting oil, chips, etc., since the opening side poses a
greater hazard of foreign matter intrusion than the other sides.
