PermaStat PLUS compounds can be used to meet the stringent ATEX Directive requirements in sensors. In order for sensors to comply with ATEX regulations, the conductive housing must have a surface resistance less than 10⁹ ohm and the ability to withstand impact testing. These thermoplastic compounds are used in capacitative sensors that are used in industrial and agricultural applications to detect both conductive and non-conductive materials — such as water, glass, plastics and metals — without physical contact. The sensors use a PermaStat PLUS 1000 Series glass-reinforced PBT compound, which is suitable for the application and fulfills the demands of the ATEX standard. This compound is permanently static dissipative and provides the necessary surface resistance to meet the ATEX requirement of less than 1 Gohm.
