Definition and terminology
Term Meaning and definition
Hysteresis
The difference between the
points when the Auto switch
turns on and off, which is
provided to prevent
chattering.
Most sensitive position
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.
Sequence controller
(PLC)
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.
Internal voltage drop The voltage applied between the COM and signal line when the Auto switch turns on.
Current leakage The current flowing to the load when the Auto switch turns off.
Load current The current flowing to the load when the Auto switch turns on.
Solid state auto switch
Auto switch which generates on and off outputs with or without mechanical contact
such as a transistor.
Reed auto switch Auto switch which generates on and off outputs with a mechanical contact.
2-wire auto switch Auto switch which has only signal line and COM line.
NPN output
Auto switch which sinks
current from the signal line
when turning on.
PNP output
Auto switch which sources
current from the signal line
when turning on.
