Inductive metal sensors are welding-field resistant
With their correction factor 1, the sensors always have the same switching distance even for different metals. In combination with extended switching distances of up to 50mm, the sensor can be used to implement a great variety of applications. The Teflon coating increases availability, especially when used in welding equipment where deposits resulting from welding spatter often have a negative effect on sensor performance. Designed for the extended temperature range of -40 to +80°C, these new sensors are also resistant to DC and AC electromagnetic fields with strengths of up to 200 mT.
In combination with large switching distances of 4 to 50mm, high switching frequencies of 1500 to 4200 Hz support high-speed applications. All four housing designs (M12, M18, M30 and 40x40mm) are available as flush and non-flush mounting variants. A switching status LED comes equipped with an error indicator activated in the event of a short-circuit or excessive temperature.
