Safety Precautions
Refer to Warranty and Limitations of Liability.
This product is not designed or rated for directly or
indirectly ensuring safety of persons. Do not use it
for such a purpose.
Never use the product with an AC power supply.
Do not use the product with voltage in excess of the
rated voltage.
Do not use the product with incorrect wiring.
Otherwise, explosion, fire, malfunction may result.
Be sure to follow the safety precautions below for added safety.
1. Do not use the sensor in an environment with explosive,
flammable or corrosive gas.
2. Do not use the sensor in an oil or chemical environment.
3. Do not use the sensor in the water, rain or outdoors.
4. Do not use the sensor in the environment where humidity is high
and condensation may occur.
5. Do not use the sensor in an environment with conditions
in excess of rated specifications.
6. Do not use the sensor in place that is exposed to direct sunlight.
7. Do not use the sensor in place where the sensor may receive
direct vibration or shock in excess of specifications.
8. Do not use thinner, alcohol, or other organic solvents on the sensor.
9. Never disassemble, repair nor tamper with the sensor.
10.Please process it as industrial waste.
1. Laying Sensor wiring in the same conduit or duct as high-voltage
wires or power lines may result in malfunction or damage.
2. Do not pull on the cable with excessive force.
3. If a commercial switching regulator is used, ground the FG (frame
ground) terminal.
4. The sensor will be available 100 ms after the power supply is turned
ON. Start to use the sensor 100 ms or more after turning ON the
power supply. If the load and the sensor are connected to separate
power supplies, be sure to turn ON the sensor first.
5. Output pulses may be generated even when the power supply is
OFF. Therefore, it is recommended to first turn OFF the power
supply for the load or the load line.
6. The sensor must be mounted using the provided nuts. The proper
tightening torque range of E3FA/E3RA plastic housing series is
between 0.4 and 0.5 N
•m. The proper tightening torque of E3FB/
E3RB metal housing series is 20 N
•m max..
