GSU14E with IO-Link: simple configuration + recipe management possible 

Often it is necessary for a single labeling machine to detect various label formats that are made of a wide range of materials. In order to avoid additional setup time or re-teaching the fork sensor when changing rolls to a new type of label, the IO-Link interface can be used to carry out a convenient format changeover to a different label type by simply uploading the respective teach value of the label to the fork sensor.

• Convenient format changeover to a different label type by uploading the respective parameter set including teach value to the fork sensor
• No setup time and no re-teaching of the fork sensor when changing rolls
• Easy format change by selecting the appropriate parameter set for the corresponding label format
• Convenient selection of the parameter set directly via the HMI (Human Machine Interface)

IGSU14E with easyTeach and ALC function 

Simple configuration via two buttons and auto complete easyTeach function. ALC (Auto-Level-Control) for automatic sensitivity readjustment during operation.

• Automatic readjustment saves repeated setting in the case of varying material characteristics of the labels or the carrier, thereby reducing system downtime
• Significantly higher functional reliability by means of switching threshold optimization
• Reduced downtimes due to material changes for labels or carriers

IGSU14E for splice detection 

Suitable for the safe detection of splices on paper, film, or plastic sheeting. With integrated paper tear detection. Simple teach process on sheet with or without moving splice. Switching signal with pulse stretching (can be switched off). Display of teach errors or paper tears via warning output or IO-Link interface.

Detection of non-transparent labels on label-carrier combinations

Requirement:
For position-accurate dispensing of non-transparent labels onto the products/packaging, it is critical to reliably detect the labels (or the gaps between two labels) on the carrier tape. Optical fork sensors must be capable of reliably detecting labels with challenging shapes (e.g., round or oval) to prevent machine downtime or inaccurate dispensing due to unreliable detection. The fork sensor must be easy to set up for all types of labels.

Solution:
The GS61 and GS63B optical fork sensors reliably detect all non-transparent labels – even those with irregular shapes and outlines. This means that machines can be fitted with only one fork sensor, regardless of the application. The fork sensors are also easy to set up, either with a potentiometer or by means of the single button teach function. The slimline-design (reduced fork height) allows the sensors to be installed close to the dispensing point.

Detection of transparent or semi-transparent labels on label-carrier combinations 

Requirement:
For position-accurate dispensing of labels onto the products/packaging, it is critical to reliably detect the labels (or the gaps between two labels) on the carrier tape. Using ultrasonic technology, the fork sensor can easily detect transparent or semi-transparent labels with challenging shapes (e.g., round or oval) to prevent machine downtime or inaccurate dispensing due to unreliable detection. The fork sensor must be easy to set up for all types of labels.

Solution:
The GSU12, GSU14E, and IGSU14E ultrasonic fork sensors can reliably detect all types of labels – whether the labels are semi-transparent or not. This means that machines can be fitted with only one fork sensor, regardless of the application. The GSX14E fork sensor, which combines an ultrasonic and an optical system in a single housing, can even reliably detect labels made from inhomogeneous cavitated BOPP material.
