FAQ

What type of reflector is required for the WL140-P430S01 to achieve its maximum sensing range?

To achieve the maximum sensing range of 5 meters, it is recommended to use a high-performance reflector like the SICK PL80A. The performance may vary with other reflector types.

How do I switch between Light-On (L.ON) and Dark-On (D.ON) modes on this sensor?

The WL140-P430S01 features a Light/Dark switching selector, typically one of the two adjustment potentiometers on top of the housing, allowing you to easily configure the output logic for your specific application.

Is the PNP output of this sensor protected against short circuits?

Yes, SICK sensors like the WL140 series typically include built-in protection features. The PNP output is protected against short-circuits and reverse polarity to prevent damage during installation or in case of wiring faults.
