Contrinex expands smart double-sheet detection portfolio

In the world of metal forming, the cost of a single error can be staggering. Accidentally feeding two sheets instead of one into a press often results in severe tool damage and substantial machine downtime. Historically, solutions to mitigate this risk have been complex and prohibitively expensive, largely relegating double-sheet detection to high-volume automotive production lines.

Contrinex has offered a more affordable solution with its double-sheet detection sensors, which were specially optimised versions of its robust 700-Series inductive sensor family. These new sensors offer a combination of performance, affordability and industrial flexibility. They are to be reconfigured to detect a range of metal sheet materials and thicknesses, making them a flexible solution for modern manufacturing environments.

Agile configuration for the modern press room

A defining feature of the new portfolio is its versatility. Unlike traditional sensors limited to specific materials, the Contrinex Smart solution is fully reconfigurable, enabling it to detect a wide range of sheet thicknesses and metals from steel to aluminium in the same production cycle.

A key advantage of the Contrinex solution is its simple and versatile configuration process, allowing users to choose the method that best fits their production environment.

The existing configuration method uses the PocketCodr configurator together with a dedicated mobile app. Technicians simply connect the sensor, enter the sheet material and thickness, and configure switching points within minutes - no programming required.

This approach remains ideal for applications where the same material is processed consistently and a quick, straightforward setup is preferred.

Direct configuration via any IO-Link master

The new sensor version introduces direct parameterisation via any IO-Link Master. This provides greater flexibility for automated production lines where different materials may be processed on the same system. Operators can easily adjust detection parameters - for example when switching between steel and aluminium sheets - without replacing or manually reconfiguring the sensor.

By offering both configuration methods, Contrinex enables manufacturers to select the solution that best matches their process and control architecture.

Engineered for harsh industrial environments

Recognising the harsh conditions typical of stamping and forming, Contrinex has utilised its "Full-Inox" technology. The sensors feature a one-piece housing made from V2A (AISI 304) stainless steel, providing maximum resistance to chemical cleaning and physical impact.

For even more extreme environments, new ActivStone coated versions offer a rugged ceramic shield to extend service life in high-wear applications.
