Indicates the instructions of unspecified prohibited
action.
WARNING
This product is not designed or rated for
ensuring safety of persons.
Do not use it for such purposes.
Precautions for Safe Use
The following precautions must be observed to ensure safe
operation.
1. Doing so may cause damage or fire. Do not install the
product in the following locations.
• Locations subject to direct sunlight
• Locations subject to condensation due to high humidity
• Locations subject to corrosive gas
• Locations subject to vibration or mechanical shocks
exceeding the rated values
• Locations subject to steam
• Locations subject to strong magnetic field or electric field
2. Do not use the product in environments subject to
flammable or explosive gases.
3. Do not use a voltage in excess of the operating voltage
range. Applying a voltage in excess of the operating
voltage range, or applying AC power to a DC Sensor may
cause explosion or burning.
4. Doing so may cause damage, fire, explosion or
malfunction.
• Never use the product with damaged body or cable.
• Never disassemble, repair nor tamper with the product.
• Never use the product with incorrect power supply or
wiring.
5. Do not short the load. Otherwise explosion or burning may
result.
6. Do not use the Sensor in environments where the cables
may become immersed in oil or other liquids or where
liquids may penetrate the Sensor. Doing so may result in
damage from burning and fire, particularly if the liquid is
flammable.
7. Do not use in water or outside.
8. When disposing of the product, treat it as industrial waste.
Precautions for Correct Use
1. Do not use the product in any atmosphere or environment
that exceeds the ratings.
2. Use M4 screws to mount the sensor and tighten each
screw to a maximum torque of 1.2 N-m.
3. Do not apply the forces on the cable exceeding the
following limits:
Pull: 40 N; torque: 0.1 N-m; pressure: 20 N; bending: 29.4 N
4. Make sure to tighten the connectors.
5. It may take time until the incident level and measurement
value become stable immediately after the power is turned
on depending on use environment.
6. Burn injury may occur. The product surface temperature
rises depending on application conditions, such as the
ambient temperature and the power supply voltage.
Attention must be paid during operation or cleaning.
If the sensing object has a metallic or shiny surface, the E3S-
R may not detect it properly. To avoid this situation, place the
sensing object so that it is not at right angles to the
Photoelectric Sensor.

● Attaching the E39-S Slit
• The Slit can be fitted vertically or horizontally as indicated
by the dotted line. Make sure that Slits for the Emitter and
the Receiver are fitted in the same orientation.
• Place the packing in the supporter and hook the claws on
the indentations in the Sensor head.
• If the supporter is contacting the mounting surface, insert a
spacer to separate it. (Refer to Slit Dimensions.)
• An operating position accuracy of 0.1 mm max. can be
achieved for a Through-beam Sensor without Slits.
