This chapter describes the features of this product, appellations and functions of each part,
andtheowofthemaintaskstousethisproduct.
1.1 Features
The linear scale will output a moving amount and displacement as digital amounts based on a linear
scale graduated in certain xed pitches.
This can precisely measure moving amounts of various instruments including electronic/semiconduc-
tor manufacturing units and machine tools.
This product is an absolute linear scale which utilizes superior electromagnetic induction resistance to
the environment.
This product measures all position coordinates from the xed origin regardless of coordinates mea-
sured just before the measurement.
Also, this product does not require an origin return step at the starting time of work or during a power
failure, and does not require batteries for backup, which will contribute much labor saving.
Moreover, this product has excellent dustproof/waterproof performance, which makes it possible for
you to use this product in harsh environments where chips or cutting oil occur.
We provide more than one type of product with di󰀨erent appearances or sizes depending on the
e󰀨ective length.

due to changes in temperature). The point to be xed rst during installa-
tion onto the machine main unit.
⑤Elastic xing parts The point to be xed later during installation onto the machine main unit.
⑥Signal cable (option) The cable to connect this product and the connection destination con-

The bend radius of the cable shall be kept within the following range.
The bend radius indicated below also applies to the case when the signal cable is extended.

→ Bend radius of the cable: 100 mm or more
Scale main unit is xed
Detector head moves
R=100 mm or more

NOTICE
If a cable bend radius exceeds the allowable range, it could result in breakage of the wires or other problems.
Also, note with caution that the scale is no longer guaranteed in such a case.
Tips
• The signal cable is an option. Also, the cable clamps or other fasteners are not supplied as accessories,
therefore, they must be prepared by the user.

2.4 Precautions on Mounting Design of Scale Unit
The following describes some design points regarding the "mounting surface" for installing the scale
unit onto the machine.
In addition, refer to "4.6 External View and Dimensional Drawings of the Scale Main Unit".
2.4.1 Datum Point Position for the Length Variation and ABS Origin
Point
The xing parts of the scale unit are divided into the full-xing parts and the elastic xing parts.
The "datum point position for length variation", which represents the reference point for the scale’s
mechanical expansions and contractions due to changes in temperature, is shown below.
Note with caution that users are not able to change this datum point position.
The internal electrical "ABS origin point" is set at 20 mm left from the edge of the e󰀨ective length.
Elastic xing parts Full-xing part Elastic xing parts
ABS origin point
Datum point position

Full-xing part
Tips
• The quantity of the elastic xing parts is di󰀨erent depending on the e󰀨ective length.
• The elastic xing parts cannot be moved horizontally.
• The system's overall temperature characteristics are stabilized by setting the behavior of the center posi-
tion in regard to the machine unit's temperature change and the scale unit’s datum point position for length
variation closer.
2.4.2 Counting Direction
When the detector head is moved rightward in the diagram below, the output serial data will increase
the count (i.e., to the + side).
