Contrinex: Transparent-object sensors with patented UV technology detect presence of clear plastic sheet during thermoforming

by donpedro

During automated packaging, high-speed thermoforming lines produce transparent plastic blister- rays from continuous reel-stock material.
Transparent-object sensors with patented UV technology detect the presence of the transparent plastic sheet as it is unwound, ensuring the material is correctly tensioned as it enters the loading station. False detection is avoided, ensuring reliable operation with little or no downtime. Ecolab-certified, these sensors are also suitable for the packaging of medical products.

Customer value
UV sensors ensure reliable detection of transparent plastic targets
Safe detection of the thinnest transparent materials
Maximum operating reserve owing to high absorption factor of UV light by transparent plastics
Elimination of multiple switching on a single target
Reliable operation without the need for manual intervention
Very low sensitivity to dust, liquid droplets and splashes
Wide operating range accommodates full range of machine geometries
Simple one- or two-step teach procedure optimizes initial sensor set-up
Sensitivity parameters are retrieved or updated remotely via IO-Link
Stability alarm highlights reduced sensitivity, avoiding unplanned stoppages

Specific product advantages
