PDA


High accuracy laser displacement sensor

PDA

Both Control output and analog output provide

Feature

  • Built-in amplifier and low-cost
  • High precision detection can be made by applying PSD(Position Sensitive Detector)
  • Protective structure is IP67
  • Easy setting(Upper limit and lower limit) can be made by pushing teaching button
  • Wide line-up with 30mm to 250mm(4 kinds) as detection distance
