D-models are typically used for measurements on objects
moving parallel to the axis of the sensor.

The output voltage function for D-model sensors includes a near range where the voltage increases with distance, an optical peak range, and a far range where the output voltage decreases with distance.

Operation at close range results in high sensitivity with a limited measuring range. Long-range operation gives moderate sensitivity with a larger measurement range.

D-type sensors are fast-acting sensors that are ideal for dynamic applications with uniaxial movement, such as those found in actuators, pistons, and valves.

  • DC-20KHz is standard
  • DC-200KHz or higher is optional
  • DC-100 Hz provides the best resolution

Standard analog sensor units include:

  • Electronics with 0 to +5 VDC output
  • 1 meter long fiber optic cable
