Provides special inductive proximity switches for special applications. Focus on TROPICAL switches over IP 69K, temperature ranges up to +120 °C and suitable for corrosive environments. High temperature switches up to 160 °C are also available. Other hot zone sensors can be used at temperatures up to 250 °C. The lower limit of temperature scale is -60 °C for POLAR switch. Sensors with large switching distances up to 170 mm and resistance to PTFE, PP or PEEK rolling oil are also available in the food industry. Atex-compliant intrinsically safe explosion-proof sensors and compact dust and gas explosion-proof sensors complete the product program.
