Note:
1. The values are for N8.5 Munsell paper.
2. The spot diameter is defined by 1/e2 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

(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.

(3) Stability (STB) Indicator
The green STB indicator is lit when the Sensor is receiving sufficient 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 counterclockwise.

Note:
1. Use a K3TX DC voltage input model.
2. K3TX models are available in various output units. Select the most appropriate K3TX model depending on
the application.
3. For details about the K3TX, refer to the K3TX
Datasheet.
4. The diagram shown here is for a K3TX model with DC
power specifications. When using a K3TX with AC
power specifications, separate the AC power supply to
the K3TX from the DC power supply to the Z4D-F04A.

Z4D-F
Correct Use
Mounting
Z4D-F04A
Install the Sensor so that the optical axis of the Sensor and the
surface of the object meet at right angles (i.e., the panel that
incorporates the light source is parallel with the object). For accurate results, it is recommended that the sensing distance is set to
the measurement point (4 mm).
Analog Output
The Z4D-04A has an output of 3 V if a sensing object is located at
the standard distance (i.e., 4±0.3 mm). The output decreases if
the sensing object is closer to the Sensor and the output
increases if the sensing object is farther from the Sensor. The
output changes by 1.6 V±10% if the sensing object moves by 1
mm. The standard upper and lower limits of the output are 6.5
and 0 V respectively. If there is no sensing object or the reflectivity
of the sensing object is low and no light is reflected to the Sensor,
the analog output will output the standard upper limit.

ON/OFF Output Diagram
Wiring
Connect the Sensor to the controlling device using an attached
sensor cable. Do not switch the power ON during wiring. Refer to
the instructions on the Sensor and the connection diagram (page
page 8) before connecting the Sensor to the controlling device.
Axis Adjustment
When the Sensor power is switched ON, the red transmitter indicator is lit. Move the Sensor so that the red beam (see the figure
below) focuses on the object. The entire light beam should be
focused on the object or an error will result.
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 counterclockwise.
If there no sensing object is present or if the reflectivity from a
sensing object is too small to reach the Sensor, the output will
turn OFF.
After the optical axis has been adjusted, tighten the mounting
screws firmly.

Precautions
Install the Sensor in a clean environment keep the filter (on the
front of the Sensor) free from oil and dust. If affected by oil or
dust, clean the Sensor as follows:
1. Use a blower brush (used to clean camera lenses) to blow
large dust particles from the surface. Do not blow the dust
away with your mouth.
2. Use a soft cloth (for lenses) with a little alcohol to remove
the remaining dust.
Do not use a scrubbing action when cleaning as a scratch
on the filter could result in the Sensor malfunctioning.
Connector
Environment
Refrain from using the Micro Displacement Sensor in a strong
electromagnetic field or in an environment where the operation of
the Sensor is subject to the reflection of intensive light (such as a
laser beam or an electric arc welding machine).
The Displacement Microsensor cannot accurately sense a mirrorlike object, a transparent object, one with an extremely small
reflection ratio, an object smaller than the diameter of the Sensor’s sensing spot, or an inclined object.
Wiring
When removing the connector from the Sensor, be sure to hold
the connector and pull it together with the attached cable.
The power supply cable for the Z4D-F04A/D should not be wired
with high-voltage lines or power lines in order to avoid interference, damage, or malfunction.
If pulled by the cable alone, it will damage the lock mechanism
inside the connector.
Do not solder wires to the Sensor connector, otherwise the Sensor may malfunction.
Interference
Others
Z4D-F04A/D Micro Displacement Sensors can be installed within
close proximity to each other and operate independently without
interference (refer to the figures below). However, if they are
installed at an oblique angle to each other, interference may
result.
Do not use switching power supplies that generate excessive
noise, which may cause sensing errors.
The following LC filter effectively reduces noise.
Sensor
Power
source
The Sensor cannot sense an object accurately if the surface of
the object consists of different materials placed next to each other
(refer to the figures below). In such a case install the Sensor so
that the boundaries of the materials and the Sensor are parallel.
When using the Micro Displacement Sensor in combination with
another type of Sensor (such as a Photoelectric Sensor), the sensor beams should be as close to perpendicular as possible.
