Characteristics
*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 (t r2 ).
*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 μ m)
(2) Output voltage converted value: 1.4 mV/μm × 40 μm = 56 mV
(for a sensor with a sensitivity of 1.4 mV/μm)
Exterior Specification
Electrical and Optical Characteristics (Ta = -10°C to 65°C)
*1. Load impedance (between OUT-GND) is set at more than 10 kΩ.
*2. t
r1: Rise time of output voltage from 10% to 90%.
*3. t
r2: Setup time from PLS rising edge to measured output value
rising edge.
