Features

Oil resistant limit switch with better reliability for applications with frequent switching in oily environment

Limit Switch with HNBR/Fluororubber for supperiour resistance to oil to prevent infiltration of moving sections.

  • HNBR/Fluororubber parts prevent infiltration of oil from moving sections 
  • Fluorine resin cable withstands cutting oil
  • Models available with SmartClick connectors 
  • Minute load model with gold cladding is optimal for electronic control
  • Approved by EN (TÜV)
  • IP67G is the degree of protection which is defined according to the Japanese Industrial Standards JIS C0920
