Pulse-signal NPN / NPN-LP: 

The F124-P is suitable for use with flowmeters which have a NPN output signal. For reliable pulse 
detection, the pulse amplitude has to go below 1.2V. Signal setting NPN-LP employs a low-pass 
signal noise filter, which limits the maximum input frequency - read par. 3.2.3.  
 

 

 
Pulse-signal PNP / PNP-LP: 

The F124-P is suitable for use with flowmeters which have a PNP output signal. 3.2V is offered on 
terminal 11 which has to be switched by the sensor to terminal 10 (SIGNAL). For a reliable pulse 
detection, the pulse amplitude has to go above 1.2V. Signal setting PNP-LP employs a low-pass 
signal noise filter, which limits the maximum input frequency - read par. 3.2.3. 
A sensor supply voltage of 8.1, 12 or 24V DC can be provided with power supply type PD, PF, PM. 
For a signal detection level of 50% of the supply voltage: please refer to "active signals".
