Preventing Chattering
• The Sensor is equipped with an anti-chattering function, but if the chattering is 100 s or longer, a faulty input may
occur. (Input signals of 99 s or shorter are ignored. Signals of 100 s or longer are treated as input signals.)
• Use no-contact output devices (e.g., SSR or PLC transistor output) for the input signals. If contacts (e.g., relay) are
used, chattering may cause the trigger to be input again during execution of a measurement.
Power Supply Specifications When a Switching Regulator Is Connected
Use a power supply that meets the following specifications. (The power supply is sold separately.)
Item
Power supply voltage
Output current
Recommended Power Supply
External power supply terminal screws
Important
Supply power from a DC power supply for which measures have been applied to prevent high voltages (e.g., a safety
extra low voltage circuit).
If UL certification is required for the overall system, use a UL Class II DC power supply.
Attaching the LED Warning Label
Attach the enclosed LED warning label to the cable or other location. The LED warning label must be attached
to a location that is readily visible from the Sensor.
