Optical Components Ideal for Non-Contact Switches

Touchless operation Resistance to water, oil, and dirt contributes to longer life

  • RPR-0521RS(SON) RPR-220
  • SIR-563ST3F SIM-040ST
  • Advantage of Optical Switches

    • Enables non-contact detection

      Utilizing reflected infrared light makes detection of
      the target object possible without contact

    • Long life unlike mechanical switches

      No direct physical contact prolongs life

    • Detects most objects

      Detects anything that interrupts the light regardless of material
