Oil-resistant structure

  • The oil-resistant NF-TR8CF and NF-TR4CF feature fiber coatings covered with fluoropolymer to prevent cutting oil from penetrating inside.
    The detection area features a structure that prevents the accumulation of cutting oil and chips, as well as an oil-resistant spherical glass lens.
