Aft er mounting is completed, turn the power on again and
make sure that the indicator (FINE) of interporator is lit in
green.
Interpolator
Use an MQ10 series interpolator (sold separately). For
information on supported servo amplifi ers, contact your
Magnescale Co., Ltd. sales representative.
Note: Connect a ground wire to the surface on which the interpolator
will be installed. Failure to make a ground connection may result in
worsened noise resistance.
Count Direction
When the head unit and scale are installed as shown below,
head unit movement to the right is the addition direction, and
to the left is the subtraction direction.

Introduction
Th
is product is a head unit for detecting the position and
amount of displacement on a straight line, and used in
combination with a SQ10 Series scale and an MQ10 Series
interpolator (sold separately).

Usage Notes
• Do not place objects that generate strong magnetic fi elds in
the vicinity of this product. Th
is could harm the accuracy
of the scale.
• Th is product should be used within an ambient temperature
range of 0 to +50 °C, and should not be exposed to direct
sunlight or heat sources.
• During operation, be sure to keep the unit 0.5 m or more
away from large power relays, high voltage or large current
switches, or other sources of noise.
• Wire the head cable and output cable separately from
power lines.
• When coupling relays, solenoids, motors or other devices
to this unit, be sure to take measures to prevent noise.
• Make sure that the external magnetic fi eld does not exceed
0.5 mT.

Head Unit Installation Procedure
Preparation
• First, install the scale. For the installation procedure, refer
to the instruction manual for the scale.
• Th
e M3 tap screws mounted on the head unit have a depth
of 6 mm. Obtain screws with a suitable length according to
the thickness of the mounting brackets. Th
e fi tting length
of the screws should be 4 to 5 mm.
Installation
1. Align the unit SmartSCALE marks on the scale and head
unit so that they are facing the same direction.
2. Th
e head unit is inscribed with a center mark that serves
as a guide to the signal detection position.
Install so that the center mark is always within the
eff ective length.
3. Set the origin so that the center mark matches up with the
center of the reference point mark on the scale.

4. Insert the supplied spacer between the head unit detection
surface and the scale, and then mount the head unit and
secure in place using M3 screws.
Th
e tightening torque should be 0.5 to 0.6 N·m.
