Warning
•Do not use this unit with voltages other than the specified supply voltage as this
may result in fire or electric shock.
•Do not perform installation work with wet hands as this may result in electric
shock.
•Do not disassemble or modify the unit as this may result in injury or damage the
internal circuits.
Caution
•Be sure to check the machine and device conditions to ensure work safety before
working on the machine.
•Be sure to cut off the power supply and other sources of drive power before in-
stalling the working on the machine. Failure to do so may result in fire or accidents.
•When turning on the power supply, etc. to operate the machine, take care not to
catch your fingers in peripheral machines and devices.

Handling Precautions
Installation precautions
When installing this unit, care should be given to the following points to prevent noise and
electromagnetic wave interference from other equipment.
1. Do not pass lead and connection cables through the same ducts as power lines.
2. Be sure to install the unit at least 0.5 m/1.6 ft or more away from high voltage or large
current sources or high-power relays.
3. Absolutely do not bring the unit near magnets or sources of electromagnetic waves.
•Magnet chucks and other sources of magnetic force of approx. 60 mT should be kept
at least 50 mm/2.0 in or more away from the shaft scale surface.
•If the unit must be installed close to sources of magnetic force, be sure to implement
adequate electromagnetic shielding countermeasures.
Installation place precautions
1. Mount the scale for more precise positioning as closely as possible to the workpiece or
to the object being measured.
(The farther the scale is mounted from workpiece, the greater the mechanical errors
grow.)
2. The scale unit should be used within an ambient temperature range of 0 to 40°C (104F°).
Avoid locations where the scale is exposed to direct sunlight and heat sources such as
motors.
3. Do not place anything on the mounted scale, or step on it: excessive force to the scale
causes trouble.
SJ300 Series
(4) (E)
Precautions for use under the following environments
1. When using water-miscible cutting fluid or when cutting non-metal
(ceramic, glass fiber, etc.) objects.
•Mount the scale so that it is not directly exposed to water-miscible cutting fluid or cutting
scraps.
•Attach a scale cover to prevent water-miscible cutting fluid mist or powder from entering
the inside of the scale.
2. When mounted on a forming machine or other machine that slides at
high speed for long periods within a specific area.
•Regularly apply oil or spray lubricant (CRC, WD40, etc.).
Be sure to implement the above measures when using the scale under the environments
noted in 1and 2above. Otherwise, quality cannot be assured.

1. Overview
1-1. Introduction
•The SJ300 series is a lineup of linear scales featuring self-adjusting reader head and a
shaft-type magnetic scale.
•A dedicated output cable (CH33-**CPD/CED) is sold separately. The length of the
output cable can be selected by the user. (Maximum cable length: 15 m/49.2 ft)
1-2. Main Features
Easy mounting
The head with self-adjusting reader head and dedicated scale bracket with wide allowable
mounting range enable the scale to be mounted in significantly less time.
No electrical adjustments
All electrical circuits, including interpolation circuits, are incorporated into the slider so that
no electrical adjustments are needed when changing the cable length or mounting the scale.
Resistant to oil and dust
The magnetic scale uses an exclusive Magnescale Co., Ltd. design for providing a structure
that is resistant to oil and dust.
