*3. tr2: Setup time from PLS rising edge to measured output value
rising edge.

*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)

Micro-displacement Sensor
• Output voltage signal is obtained by applying the pulse
signal at PLS terminal. Please be careful, it is not obtained
by DC voltage applying.
