Note: 1. The FS (Full Scale) value (listed in the preceding table) is calculated as follows:
Example: 1% FS on the Z4M-W40RA
Distance full scale conversion: 20 mm x 0.01 = 0.2 mm
Voltage full scale conversion: 16 mA x 0.01 = 0.16 mA

Current full scale (The value changes according to the span to be adjusted.)
2. The linearity of the sensor is checked with a white
alumina ceramic object. The peak-to-peak value
deviated from the displacement linear output
voltage is within the specified range, as shown in
the graph. The deviation value may vary with the
object. (Refer to the preceding table.)

The spot diameter is defined by 1/e
There is light leakage outside the defined spot, and the environment of the object may
influence sensing accuracy. Reduce the influence of the environment as much as
possible. (Refer to spot diameter within the ENGINEERING DATA )

3. The response speed of the sensor is the time
required for the analog displacement output to
increase from 10% to 90% of the full value (at the rise
time) or decrease from 90% to 10% of the full value
(at the fall time). To decrease the error ratio to within
1% at the rise time, the time required will be two or
three times as long as the specified value. (Refer to
the preceding table.)
