Increase the availability of your systems and reduce maintenance and storage costs at the same time. Weld-resistant inductive sensors from Balluff detect metallic objects such as steel, aluminum or brass with identical switching distances. With their ceramic coating, they are just as resistant to metal splashes, slag and combustion residues as they are to magnetic fields that arise from electrical welding currents of up to 25 kA. They are also resistant to abrasive media and cleaning agents. Perfect for use in welding and induction hardening systems and in similarly harsh industrial environments.
