New inductive sensors from wenglor

New inductive sensors from wenglor

wenglor has launched eight new inductive sensors, now available with a Teflon coating.

With switching distances of up to 50mm and magnetic field resistance of 200 mT, the new inductive sensors come with correction factor 1.

The new welding-field resistant models feature four housing designs and, said wenglor, offer impressive performance for the detection of ferrous and non-ferrous metals.

Inductive sensors with correction factor 1 detect ferrous metals, as well as non-ferrous metals such as copper, cobalt, nickel and tin. Due to a special functional principle, the sensor always has the same switching distance even for different metals.

Together with extended switching distances of up to 50 mm, the sensor can be used to implement a number 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. The extended temperature range of -40 to +80° C also permits use in very cold and very hot environments.

wenglor product manager Jens Bußhart explained: “Fundamentally, these sensors are suitable for all industry sectors where all types of metal need to be reliably detected. But the new sensor series is exceptionally well suited especially in the steel industry for the production of castings, and for welding zones in the automotive industry (auto body fabrication, pressing plants, chassis components). New welding processes continuously result in new requirements, for example with regard to magnetic field resistance – and we’re right on track with our product range.”
