Cautions during Use
• Follow instructions in 'Cautions during Use'. Otherwise, It may cause unexpected
accidents.
• 12 - 24 VDCᜡ power supply should be insulated and limited voltage/current or Class
2, SELV power supply device.
• Use the product, 1 sec after supplying power. When using separate power supply for
the sensor and load, supply power to sensor first.
• When using switching mode power supply to supply the power, ground F.G. terminal
and connect a condenser between 0 V and F.G. terminal to remove noise.
• When connecting a DC relay or other inductive load, remove surge by using diodes
or varistors.
• Wire as short as possible and keep away from high voltage lines or power lines, to
prevent surge and inductive noise.
• This unit may be used in the following environments.
- Indoors (in the environment condition rated in 'Specifications')
- Altitude max. 2,000 m
