2% F.S. (full scale) max.
Value
Note: 1. Distance from the mounting reference plane.
2. “Sensitivity” is defined as “inclination of divided output line” and the variation value between individual products of fluctuating divided out-
put voltage per unit length.
V2 − V0
Sensitivity =
2000
(mV/mm)
Where
V0: Output voltage when d = 5.5 mm
V2: Output voltage when d = 7.5 mm
d: Distance from reference mounting plane to an object.
3. Value of electrical noise range of divided output signal converted to distance under the following conditions.
Sensor
Sample and hold circuit
Oscilloscope
(1) Ripple noise of power supply: 10 mV p-p max.
(2) Sampling time of the sample and hold circuit: 50 µsec
(3) Distance to object: Distance from the reference mounting plane is 6.5 mm±1 mm.
** When the testing conditions are deviated from the above conditions, resolution changes. For details, please consult OMRON
sales representative.
4. The peak-to-peak value of the output error from the ideal line.
Calculation, based on a linearity of 2% F.S., is as follows:
(1) The conversion value based on the full scale distance: 2 mm × 0.02 = 0.04 mm (40 µm)
(2) The conversion value based on the output voltage: 1.4 mV/µm × 40 µm = 56 mV
(When the product sensitivity variation is 1.4 mV/µm.)
C: Virtual line parallel to B.
D: When sensitivity of a sensor is 1.4 mV/mm,
linearity must be equal or less than 56 mV.
Linearity
A: Actual output curve.
B: Straight line that
connects V0 with V1.
