from top manufacturers
Fork sensors (slot sensors) operate using a through-beam design. Nevertheless, the alignment and adjustment are redundant as the transmitter and receiver are both integrated into a single housing. They enable you precise, fast, and reliable detection of a wide range of material combinations and surfaces in many applications, most typically in labelling.
Detect reliably with top-quality Fork Sensors
With their precise, focused beam, different fork sensor variants offer key advantages when it comes to accurate and stable detection of different labels, double sheets, and objects. The additional advantages are their easy mounting and high ambient light immunity.
We offer you wide line of fork sizes, designs, and operating principles, from light (infrared, red light, laser) to ultrasonic and to capacitive, manufactured by world’s leading companies:
Benefit from precision, flexibility, and simplicity
Fork sensors represent a combination of transmitter and receiver in one fixed U-shaped housing.
Different detection methods accommodate all kinds of applications
Fork Sensors include sensors for object detection and sensors for label detection.
To provide precise detection of objects and a wide variety of labels, these sensors use different detection methods:
Effectively automate product labelling with Fork Sensors
The most common application in which you can use slot sensors is label detection in labelling machines.
In the packaging industry, product labelling is mostly automatic, and labels come in various formats, sizes, materials, and textures.
The time for the accurate placement of the label is usually very limited.
Label placement stands for the precise positioning of the label on the product or packaging, even at high conveyor speeds.
To achieve this kind of placement precision, it is crucial that the labels are reliably detected. Slot sensors provide such detection in application including processing and packaging machinery and automatic labellers.
With a reliable detection of labels of a wide range of materials and textures you can enable high machine throughputs and prevent downtime. Sensors that boast short setup time provide higher production volumes.
Web material is generally processed from a roll, but the splice can be hidden somewhere in the roll.
Some fork sensors with integrated paper tear detection enable safe detection of splices on paper, film, or plastic webs.
In special Teach-in method of these sensors only the sheeting is learned. When the sensor detects the level difference at the splice, it sets its output.
Take advantage of innovative functions and increase productivity
The same labelling machine often needs to detect various label formats made of a wide range of materials. Fork Sensors with IO-Link offer you a whole range of useful functions, from configuration and operation to control. They allow you to reduce machine downtimes and changeover times when switching products, more machine flexibility, and the prevention of false settings.
Also, the parameters that are stored in the IO-Link master or in the control system guarantee machine availability and provide recorded and documented replacement processes. You can use the IO-Link interface to simply upload the appropriate teach value of the label onto the fork sensor, making it suitable for another label type.
Integrate Fork Sensors into automation network
Benefit from the advanced functions of fork sensors with IO-Link and increase a plant or machine productivity by integrating these sensors into automation network. Here are some great non-labelling options on how to use sensors’ functions in automation:
