Preventing Chattering
• The Sensor is equipped with an anti-chattering function, but if the chattering is 100 µs or longer, a faulty input may
occur. (Input signals of 99 µs or shorter are ignored. Signals of 100 µs 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., a 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. (They are sold separately.)

Power supply voltage
Recommended Power Supplies
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.
