Internal circuit diagram
*1 ON voltage/ON current
This is the voltage value or current value that makes the signal go OFF to ON.
The ON voltage value becomes the potential difference between COM IN 1/2 and the input terminals.
*2 OFF voltage/OFF current
This is the voltage value or current value that makes the signal go ON to OFF.
The OFF voltage value becomes the potential difference between COM IN 1/2 and the input terminals.
*3 Below is a table giving the COM_IN (input common) and input signal connection correspondence.

Chattering countermeasures
• The sensor is designed with functions to deal with chattering, but if chattering of 100 Ps or more
occurs, incorrect input due to chattering cannot be prevented. (Input signal changes of less than 100
Ps are ignored. The input signal is applied when the same level is maintained for 100 Ps or longer.)
• Always use non-contact relays (SSR, PLC transistor output) for input signals. If contact relays are
used, contact bounding may input a trigger again during measuring.
