Simple and precise setting of the switching threshold via IO-Link, teach-in button, or plus/minus buttons
Light/dark switching function
Fast response time: 50 μs
PNP or NPN switching output
Plastic housing with IP 65 enclosure rating
Smart sensor with integrated IO-Link interface

Flexible and simple mounting directly on the edge of a label dispenser ensures a high level of accuracy in the process
Small housing allows simple installation even where space is limited
User-friendly adjustment allows easy and quick commissioning
Fast response times enable precise detection – even at very high track speeds
Thanks to IO-Link or external teach-in, the switching threshold can be adapted while the process is running, increasing process reliability
Easy to access data from the PLC via IO-Link

The slim, forked shape of the WFS has been specially developed for the requirements of the labeling process. The design allows the sensor to be mounted directly on the edge of a label dispenser. Difficulty in detecting the label gap is finally eliminated – the sensor's switching threshold can be taught-in while the label strip is running. This sophisticated operating concept means the sensor can be adjusted to different labels quickly, easily, and reliably. The fast response time guarantees exceptional repeat accuracy.
