Characteristics(Ta = 25°C)
Object: N8.5 Munsell paper with a reflection factor of 70%.
Operating area (see note 1) 6.5 ± 1 mm
Sensitivity variation (see note 2) -1.4 mV/µm ±10% max.
Resolution (see note 3) ±10 µm max.
Linearity (see note 4) 2% F.S. (full scale) max.
Note: 1. Distance from Mounting Reference Plane to Target.
  2. The sensitivity is defined as slope of the line and it represents the variation in the output voltage per unit length between different products.
  3. This is the value of the electrical noise width in the output signal converted to a distance under the following conditions.
(1) Noise width is measured in a waveform after the four times average with an oscilloscope.
(2) Ripple noise in the power supply voltage (Vcc): 10 mVp-p max.
(3) Distance from mounting reference plane to target: 6.5 mm
(4) Resolution is measured by the voltage of response delay time (tr2).
  4. This is the peak-to-peak value of the deviation of the signal output from a straight line.
A linearity of 2% F.S. indicates the following value:
(1) Distance full-scale converted value: 2 mm × 0.02 = 0.04 mm (40 µm)
(2) Output voltage converted value: 1.4 mV/µm × 40 µm = 56 mV
(for a sensor with a sensitivity of 1.4 mV/µm)
