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.
