● Other Precautions

• Do not disconnect wire the cables from the Sensor when power is

supplied to the Sensor, or Sensor damage could result.

• Do not install the Sensor in the following places to prevent

malfunction or trouble:

1. Places exposed to dust or oil mist

2. Places exposed to corrosive gas

3. Places directly or indirectly exposed to water, oil, or chemicals

4. Outdoor or places exposed to intensive light, such as direct

sunlight

• Be sure to use the Sensor under the rated ambient temperature.

• The Sensor may be dissolved by exposure to organic solvents,

acids, alkali, or aromatic hydrocarbons, aliphatic chloride

hydrocarbons causing deterioration in characteristics. Do not

expose the Sensor to such chemicals.

• Make sure the total length of the power cable connected to the

product is less than 10 m.

• Only output 2 (OUT2) on NPN models is provided with overcurrent

protection.

If an overcurrent occurs, heat generated by the output transistor will

activate the thermal shutdown circuit and OUT2 will turn OFF.

Check the wiring and load current and cycle the power supply. If

there is no overcurrent, normal operation will be resumed. (The

thermal shutdown circuit will be activated again if there is an

overcurrent.)

This function does not provide protection against load short circuits.

If the electric power of the output transistor increases due to a load

short-circuit or near load short-circuit, the Sensor may be damaged.

• An output pulse may occur when the power supply is turned ON

depending on the power supply and other conditions. The operation

of the Sensor will be stable 100 ms after turning ON the power

supply.
