3.1.Transistor Signal Output NB:

NPN Normally Closed – low-level output (0V) during standard light transmission, with no output when obstructed. NK: NPN Normally Open – no output during standard light transmission, output of 0V when obstructed. PB: PNP Normally Closed – high-level output (24V) during standard light transmission, with no output when obstructed. PK: PNP Normally Open – no output during standard light transmission, output of 24V when obstructed.

3.2.Relay Signal (available for select series)

A signal relay is integrated within the grating, providing passive switching in either normally open or normally closed configurations. Digital 485 signals, voltage/current analog signals are also available; please consult with us for further information.
