Instruction Manual
• The ES-M1/M2 are intended for target detection. Do not use
these products in a safety circuit for protecting the human
body.
• The ES-M1/M2 are not explosion-proof. Do not use these
products in an environment where inflammable gas, liquid or
powder is present.

FEATURES
■ One-line connection system
See “MOUNTING SEVERAL AMPLIFIERS” on page 2.
A wire-saving sensor system can be established by combining other
one-line connection amplifiers such as the FS-V10 Series or LV
Series.
■ Easy connection with the European terminal
See “SENSOR HEAD CONNECTION” on page 1.
The sensor head is connected to the amplifier through the European
terminal, allowing easy and quick connection.
■ Disconnection alarm indicator & output
See “PART NAMES AND FUNCTIONS” on page 1.
The alarm indicator and output turn on when the sensor head is
disconnected, enabling quick discovery of abnormal condition. (The
ES-M2 features the indicator only.)
■ Mutual interference suppression function
See “MUTUAL INTERFERENCE SUPPRESSION” on page 2.
Mutual interference among several sensors that are used in close
proximity can be suppressed by a simple operation.
ACCESSORIES
Instruction Manual: 1 End unit: 2 (ES-M2 only)
Metal screwdriver: 1 Cautions sticker: 1 (ES-M2 only)
Mounting bracket: 1 (ES-M1 only)
SENSOR HEAD CONNECTION
1. Modify the end of the sensor
cable as illustrated on the right.
Be sure to tightly twist the shield
wire and core wire separately.
* When the outer sheath is stripped, the shield wire appears around the core
wire. Separate the core wire and shield wire before modifying the cable.
2. Turn the terminal block tightening
screws counterclockwise to loosen
them.
3. Insert the sensor cable straight into
the insertion port of the amplifier.
Make sure that the core wire and
shield wire are inserted into the correct
ports and that the cable does not twist.
4. Turn the terminal block tightening
screws clockwise to tighten them. Be
sure to limit the tightening torque to
0.15 N•m.
5. Turn ON the amplifier and check that
the disconnection alarm indicator
remains OFF. If the indicator is ON, go
back to step 1 and repeat the
procedure again.
MOUNTING AMPLIFIER
■ Mounting/Detaching the amplifier to/from a DIN rail or
the mounting bracket
Hook the claw located at the amplifier cable side onto the DIN rail, and
then hook the front side claw to the rail while pressing the amplifier
forward. To detach the amplifier, unhook the front claw by lifting the
amplifier front side while pressing it forward.
Mounting Detaching
■ Side mounting
Using the side holes of the supplied mounting bracket (ES-M1 only),
fix the amplifier with screws.
