
Use of 3-wire PNP proximity switches is preferred.

Use of 3-wire NPN proximity switches needs an additional
external pull-up resistor


Use of 2-wire proximity switches is possible.
Consider a minimal load current of approximately 5mA should be
complied. Depending on 2-wire proximity switch an additional
parallel resistor is necessary.
