The new WFS Fork Sensor launched by SICK (UK) brings new precision to label
printing for packaging and other production operations. Designed
specifically to be mounted at the outlet of the label dispenser, it
accurately detects label location and interval on the substrate, allowing
rapid adjustment to different label runs with exceptional repeat accuracy.
The SICK WFS's compact design provides edge detection of non-transparent
labels on different web materials, and also double sheet fed incidents. The
50µs response time ensures rapid reaction at high web speeds, and fast
response to adjustments.
New labels can be taught-in remotely via a PLC or control panel during
operation and on-sensor controls provide fine tuning, and the light / dark
switching function enables rapid contrast switching.
The plastic housing allows easy mounting over the edge of the label strip,
and is environmentally protected to IP65, to ensure long reliable sensor
life under production conditions.
