Note:
1.
The values are for N8.5 Munsell paper.
2.
The spot diameter is defined by 1/e
2
of the Sensor’s laser beam center. Although a sub-beam may be observed around the main
beam, this does not mean that the product is defective.
3.
Refers to input impedance of a device to be connected.
4. Resolution (Z4D-F04A)
The resolution is the peak-to-peak displacement conversion value of the analog displacement output (Conditions: N8.5 Munsell
mat paper at the center of measurement point with a power ripple noise of 10 mV (p-p) max.)
Output fluctuation
5.
The value is the peak-to-peak error rate of a displacement output voltage line with N8.5 Munsell mat paper. The value varies
with the sensing object.

6. Response Time (Z4D-F04A)
The response time of the Sensor (Z4D-F04A) 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).

(1) Power (PWR) Indicator
The green PWR indicator is lit when power is properly supplied to
the Sensor.
(2) Alarm (ALM) Indicator
The red ALM indicator is lit if there is no sensing object or the
reflectivity of the sensing object is low and it is impossible for the
Sensor to process the light reflected to the Sensor. The indicator
is lit when the amount of light is less than what is required for
computation by the Sensor. When the ALM indicator is lit, make
necessary adjustments so that the indicator turns OFF.
Appropriate amount of light:
Insufficient amount of light:

(3) Stability (STB) Indicator
The green STB indicator is lit when the Sensor is receiving suffi-
cient light to process. If the indicator is not lit, adjust the amount of
light to turn on the indicator.
(4) Operation (OPE) Indicator
The Sensor is synchronized with the ON/OFF output and the
orange OPE indicator is lit when the Sensor has ON output.
(5) Distance Adjustor
The ON/OFF position can be set with the distance adjustor if a
sensing object is at the sensing range (i.e., 4±1.25 mm). The ON/
OFF position will shift farther from the Sensor if the distance
adjustor is turned clockwise and the ON/OFF position will shift
closer to the Sensor if the distance adjustor is turned counter-
clockwise.
