Precaution when using LED-equipped limit switch
5.4.2 Output Wiring
Do not connect a load that exceeds the maximum swiching ability to the output terminal.
Protective circuit for inductive loads
• With an inductive load, a protective circuit should be installed in parallel with the load.
• When switching DC inductive loads with relay output type, be sure to connect a diod across the ends of
the load.

If the input of PLC does not turn off because of
the leakage current from the LED-equipped limit
switch, the use of a bleeder resistor is
recommended, as shown below.
