■ In the case of 2-wire proximity switch
Use a two-wire proximity switch whose leakage current, I is 1.5 mA or less when the switch is off.
If the resistance is larger than leakage current, I of 1.5 mA, connect a bleeder resistance Rb (kΩ), obtained by the following
formula as shown in the following figure.
