Normally open, normally closed or antivalent
Which output function is required?
Which output function is required? Binary switching sensors – i.e. ones that are in either the 'switched on' or 'switched off' state – have three different output functions: 'normally open', 'normally closed' and 'antivalent'.
Normally open

Normally closed

Antivalent

In summary:
If additional sensor data are required, there are many sensors available that provide an analogue output or are compatible with the new IO-Link interface.
