Double-Sheet Detection Sensors aim to eliminate costly tool damage in press lines by ensuring that only single-sheet blanks are fed to the presses.
Contrinex’s innovative, robust Smart Inductive sensors were introduced to the challenges of double-sheet detection on press lines. At the end of 2023, the CBM’s Metal Matters magazine carried an article describing their use by a press tool engineer to create a low-cost and adaptable double-sheet detection system.
In response to customers’ requests, Contrinex has simplified things by launching dedicated Double-Sheet Detection Sensors and a specialised configuration app. The setup is now straightforward, and it takes less than 90 seconds to follow the app prompts on a phone or tablet. For example, setup can now be done within the remit of a setter/operator rather than needing the deeper knowledge of a maintenance engineer.
The SMART Double-Sheet Detection Sensors are uniquely robust, with the sensor’s front face and sides being machined from a single piece of V2A (AISI 304) stainless steel. To further protect the sensors from damage, they can detect sheet materials between 3 and 5 mm away. Providing a contactless solution extends sensor life and can also provide advantages in reducing potential contamination.
Available as either M18 or M30, the sensors can detect steel, aluminium, or stainless steel sheets. Material thickness can vary from a minimum of 0.2mm to a maximum of 4mm for aluminium or a range of 0.5 to 2mm for steel, for example.
Fast configuration using the hand-held PocketCodr communication module and a phone or tablet enables the sensors to work with multiple materials and sheet thicknesses. Contrinex’s SMART Double-Sheet Detection Sensors offer a flexible and easy-to-use solution at a much lower cost than other systems, perhaps enabling double-sheet detection to be applied where it was not previously affordable.
