Cautions during Use
• Follow instructions in 'Cautions during Use' . Otherwise, It may cause unexpected
accidents.
• When connecting an inductive load such as DC relay or solenoid valve to the output,
remove surge by using diodes or varistors.
• Use the product after 0.2 sec of the power input.
When using a separate power supply for the sensor and load, supply power to the
sensor first.
• 12-24 VDCᜡ power supply should be insulated and limited voltage/current or Class 2,
SELV power supply device.
• Wire as short as possible and keep it away from high voltage lines or power lines to
prevent surge and inductive noise.
• When using switching mode power supply (SMPS), ground F.G. terminal and connect
a condenser between 0V and F.G. terminal to remove noise.
• When using a sensor with a noise-generating equipment (e.g., switching regulator,
inverter, and servo motor), ground F.G. terminal of the equipment.
• This unit may be used in the following environments.
- Indoors (in the environment condition rated in 'Specifications')
- Altitude max. 2,000 m
- Pollution degree 3
- Installation category II
