Definition and terminology
Terms
Meaning
2-wire auto switch
Auto switch which has only signal line and COM line.
Current leakage
Current applied to the load when the switch is turned off.
Difference between ON and OFF point which are to prevent chattering.
This is called hysteresis.
Hysteresis
Internal voltage drop
The voltage applied between COM and signal line when the switch is turned on.
Load current
Current applied to the load when the switch is turned on.
Most sensitive position
Indicates the center position of the sensor (most sensitive), and becomes the center of
operating range.
Auto switch which absorb current from the signal line during ON status.
NPN OUTPUT
Auto switch which output current from the signal line during ON status.
PNP OUTPUT
Reed type auto switch
Auto switch to output ON-OFF by mechanical contact.
Sequence controller
(PLC)
Device to control the sequence.
Input the Auto switch signals according to the program and output them to the other
device.
Solid state auto switch
Auto switch to output ON-OFF regardless of the presence of mechanical contact such
as transistor.
