Glass or Transparent Object Detection

ASG Series

  • Reliably detects inclined transparent glass
    Ideal for flush-mounting in robot end-effecter.
  • Unique optical system allows stable detection regardless of warpage or inclination of glass
    Unprecedented reliability in inclined object detection is realized by the use of two red LED light sources
  • Thin (4mm) embedded amplifier photo sensor
    Counterbores for M3 countersunk screws convenient for flush-mounting in robot end-effecter.

More Info

Difference between ASG-S20R and ASG-Z15R

  • ASG-S20R is a diffuse reflective type sensor with a wide activation range.
    If the detected glass is warped, the detecting distance can be 25 mm at maximum.
  • ASG-Z15R is a convergent reflective sensor with a wide activation range.
    If the glass to detect is warped, the detecting distance can be 18 mm at maximum.
    The sensor is not activated by transparent glass in contact with the sensor.

ASG-S20R

ASG-S20RV

  • No mounting bracket is provided.
  • The tightening torque should be max 0.15 N?m.

NPN output

PNP output

  • The output transistor turns off when load short circuit or overload occurs.
    Check the load and turn the power back on.
