These inductive sensors only detect ferrous metals. Aluminium chips which build up on the active face during the process and lead to incorrect switching of conventional sensors are ignored due to this principle.
The sensor is resistant to oil and coolants thanks to a special design, additional seals and a stainless steel sensing face. This results in a long life.
During installation, the reinforced housing allows a tightening torque which is up to two times higher than that of standard sensors. Due to the permanently legible laser type label the unit can still be clearly identified after many years.
