WFS

Product descriptionThe slim, forked shape of the WFS has been specially developed for the require-ments of the labeling process. The design allows the sensor to be mounted directly on the edge of the dispenser.

Difficulty in detecting the label gap is finally eliminated – the sensor’s switch-

ing threshold can be taught-in while the label strip is running.

The improved operating concept means the sensor can be adjusted to different labels quickly, easily and reliably.

The fast response time guarantees exceptional repeat accuracy.

at a glance • Optimized housing with slim fork

shape • Dynamic teach-in via teach or control

panel and manual fine adjustment with “+”/“–” buttons

• Light/dark switching function

• Fast response time of 50 µs • PNP or NPN • IP 65 plastic housing • Switching output also during teach-in

active

Your benefits • Slim design allows flexible mounting

close to the dispenser of the label which ensures higher accuracy in the process

• Compact housing ensures space-saving installation

• User-friendly adjustment allows easy and quick start-up

• External teach-in allows automatic threshold adjustment via the PLC during the process which ensures reliable detection all the time

• Short and fast response times enable precise detection – even at high web speeds

Setting the switching threshold via teach-in (dynamic)

Press “–” button, teach-in process is finished.

2. Move multiple labels through the fork sensor

Notes

Teach-in (static): Setting the switching threshold without movements of label, cf. operating instruction.

Press both the “+” and “–” buttons together, hold > 1 s and than release the teach-in buttons. The red LED flashes.

1. Position label or substrate in the active area of the fork sensor

Once teach-in process is complete, the switching threshold can be adjusted at any time using the “+” or “–” button. To make minor adjustments, press the “+” or “–” button once. To configure settings quickly, keep the “+” or “–” button pressed for longer.

Switching threshold adaptation:Only, the first teach-in procedure after switching on is permanently stored. Teach-in can be repeated cyclically. Switching output also during teach-in active.

Press both the “+” and “–” buttons together (3 seconds) to lock the device and prevent unintentional actuation.

Press both the “+” and “–” buttons together (6 seconds) to define the switching function (light/dark switching). Standard setting: Q = light switching.
