The inductive factor 1 sensors from Balluff detect all metals with high precision and are particularly impressive where different types of metal are being worked with. They offer long switching distances without a reduction factor and are resistant to magnetic fields, making them suitable for areas with strong electromagnetic fields - for example in welding systems. For these harsh environments, you can also get corresponding versions with an extremely resistant coating against welding spatter.
