Inductive sensors with selective behavior – intelligently distinguishing metals

In industrial automation, the precise differentiation of materials is often crucial. Inductive sensors with selective behavior offer an intelligent solution for differentiating between different metals – without any contact or wear.

What are inductive sensors with selective behavior?

Inductive sensors with selective behavior from wenglor in the cubic format. — Inductive sensors with selective behavior distinguish ferromagnetic metals from non-ferromagnetic materials.

Inductive sensors detect metal objects through electromagnetic induction. The selective variant of these sensors goes one step further: they differentiate specifically between ferromagnetic and non-ferromagnetic materials.

Ferromagnetic metals: e.g. iron, steel
Non-ferromagnetic materials: e.g. aluminum, brass, copper, stainless steel

This differentiation is based on the specific electromagnetic properties of the materials and enables precise and reliable material detection.

Practical example: Sorting cans

Two cans are detected in a deposit bottle machine by an inductive sensor. — Inductive sensors with selective behavior can reliably distinguish cans with different metals.

A classic example of the use of selective sensors is the automatic sorting of beverage cans:

The sensor for non-ferromagnetic materials only detects aluminum cans.
The sensor for ferromagnetic metals only reacts to steel cans.

This selective detection makes it possible to reliably separate different can materials, which considerably simplifies the automation of sorting processes.

Typical applications

Inductive sensors with selective behavior from wenglor are used in various applications:

Automated sorting systems: e.g. in the beverage industry for separating cans made of different metals
Quality control: Monitoring of production processes in which the material composition is crucial
Recycling plants: separation of metals for recycling

Why inductive sensors with selective behavior are so important

The ability to distinguish between metals opens up numerous advantages:

Higher accuracy in sorting and inspection processes
Efficient quality control in production
Automated processes that do not require manual intervention
Reduced error rate thanks to clearly defined sensor properties

Conclusion

Inductive sensors with selective behavior from wenglor offer an efficient and reliable solution for material detection in industry. Thanks to their ability to distinguish between different metals, they help to optimize production processes and increase quality assurance.
