UV Sensor

This sensor is a photodiode (PD) made of silicon that can detect ultraviolet light at high sensitivity.
The output current changes in reaction to light which includes ultraviolet light.

  • Calculating the difffference between the two outputs enables detection of ultraviolet components without a fifilter.
  • The industry’s smallest-class* transparent resin package 2.55×1.56×t0.65(max.) mm
  • The industry’s highest-class* sensitivity 0.170A/W (λ=365nm)
