Model:E3JK

omron photoelectric sensor switch E3JK

  • Built-in amplifier that can accept a wide range of supply voltage.
  • Slim and compact design with dimensions: 50 x 50 x 17.4 mm.
  • High switching capacity (3A, 250VAC) along with replay outputs and better life expectancy.
  • Uses a red light indicator.
  • Sensing distance varies from 30cm to 5m for different models.
  • Comes with two operation modes: Light-ON and Dark-On
  • Models with both adjustable and fixed sensitivity available.
  • For detection of shiny or glossy objects, models with polarized reflective type are also available.
