Handling during Wiring
1. If a force is applied to the connection area between the terminal
and connector by bending or pulling the cable after the wiring is
completed, the connector contact part or connection area with the
cable may be damaged, resulting in contact failure. Make sure that
a stress (external force) as shown in the figure below is not applied
to the connection area between the terminal and connector when
routing and connecting cables or harnesses.
2. Do not perform cord wiring when power supply voltage is applied.
Doing so may result in damage.
Other Precautions
Make sure the total length of the power cable connected to the
product is less than 10 m.
Design
Design should be made so that light is completely shut off during
operation. We recommend that sensing objects are made of metal.
(With an infrared light sensor, infrared light will pass through the
sensing object made of resin, resulting in unstable detection.)
Connection with PLC (NPN Open Collector Type)
Mounting should be carried out by reference to the figure below.
Connection with Counter (NPN Open Collector Type)
Mounting should be carried out by reference to the figure below.
1. Non-voltage input
2. Transistor input (voltage input)
* For details on external resistance calculation, see the text.
Others
1. Do not connect or disconnect the connector while power is
applied. Doing so may result in breakage.
2. Do not mount the sensor in the following places because doing so
may cause malfunction or damage.
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
5) Make sure that the operating ambient temperature is within the
rated range.
3. The sensor may be dissolved by exposure to organic solvents,
acid, alkali, aromatic hydrocarbon, and chlorinated aliphatic
hydrocarbon solvents, causing deterioration in the characteristics.
Do not expose the sensor to such chemicals.
4. An output pulse may occur when the power supply is turned ON
depending on the power supply and other conditions. Use the
sensor in the stable ready-for-detection state reached in 100 ms
after turning on the power supply.
