EX-20 photoelectric sensor

  • EX-20 photoelectric sensor

Ultracompact photoelectric sensors (side sensing)

Using a single chip optical IC we created the powerful EX20 sensors, which are among the smallest photoelectric sensors worldwide. In spite of their miniature size, the sensors incorporate a sensitivity adjuster. Since a red LED dot light source is used, alignment and confirmation of the sensing position is easy, even if very tiny objects have to be detected.

Characteristics:

  • Miniature construction
  • Response time only 0.5ms
  • Red LED
  • New: up to 35% less power consumption
  • New: improved ambient light immunity
  • Adjustable sensitivity
  • Thru-beam
  • Diffuse reflective
  • Sealed to IP67
  • 2 indicator LEDs

Accessories:

  • Slit masks
  • Reflectors
  • Mounting bracket

Ultracompact photoelectric sensors (front sensing)

EX-20 series sensors expand our innovative and super slim photoelectric sensors which combine high performance and miniature design. EX-20 sensors can be fastened with M3 screws. Moreover, metal inserts have been provided in the mounting holes, thus the sensor will not be damaged even if the screws are overtightened.

Characteristics:

  • Response time only 0.5ms
  • Red LED
  • New: up to 35% less power consumption
  • New: improved ambient light immunity
  • Thru-beam
  • Diffuse reflective (fixed focus)
  • Sealed to IP67
  • Two-color indicator LED

Accessories:

  • Slit masks
  • Mounting brackets
