NPN output
PNP output
The difference between the
points when the Auto switch
turns on and off, which is
provided to prevent
chattering.
The center position of the sensor unit (which gets the strongest reaction of the sensor
unit), which means the center position of an operating range as well.
The device to perform sequence control, which performs controlling such as receipt of
inputs from the Auto switch along with programming and sending of the output to other
machines.
The voltage applied between the COM and signal line when the Auto switch turns on.
The current flowing to the load when the Auto switch turns off.
The current flowing to the load when the Auto switch turns on.
Auto switch which generates on and off outputs with or without mechanical contact
such as a transistor.
Auto switch which generates on and off outputs with a mechanical contact.
Auto switch which has only signal line and COM line.
Auto switch which sinks
current from the signal line
when turning on.
Auto switch which sources
current from the signal line
when turning on.
