Safety Precautions
Refer to Warranty and Limitations of Liability.
WARNING
This product is not designed or rated for ensur-
ing safety of persons either directly or indirectly.
Do not use it for such purposes.
Precautions for Correct Use
Make sure that this product is used within the rated ambient
environment conditions.
●
Installation
• Mount the Sensor with two M3 screws, using plain washers
and spring washers to ensure the screws will not become
loose. Use a tightening force of 0.54 N·m max.
●
Wiring
Unused Output Lines
Be sure to isolate output lines that are not going to be used.
Wiring method
Connection is made using a connector. Do not solder to the
pins (leads). The pins (leads) are soldered to the internal
board of the Sensor. Therefore, direct soldering of the pins
(leads) may result in an internal disconnection causing mal-
function.
●
Others
• The power cable connected to the Sensor must not be more
than 10 m in length.
• Only output 2 (OUT2) on NPN models is provided with over-
current protection.
If an overcurrent occurs, heat generated by the output tran-
sistor 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 opera-
tion 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 increas-
es 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 turn-
ing ON the power supply.
Precautions for Safe Use
●
Operating Environment
These Photomicrosensors have an IP50 (conforms to IEC)
enclosure and do not have a water-proof or dust-proof struc-
ture. Therefore, do not use them in applications in which the
sensor will be subjected to splashes from water, oil, or any
other liquid. Liquid entering the Sensor may result in malfunc-
tion.
