Specifications
■Ratings/Characteristics
Note: 1. The values are for N8.5 Munsell paper.
2. The spot diameter is defined by 1/e2of 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.)
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.

Nomenclature
■Analog Output (Z4D-F04A)
(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: Not lit
Insufficient amount of light: Lit in red
■ON/OFF Output (Z4D-F04D)
(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.

Z4D-F04A and K3TX-VD
Note: 1. Use a K3TX DC voltage input model.
2. K3TX models are available in various output units. Se-
lect 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.

!Caution
Item Examples
Power supply
Do not impose an excessive voltage on the
Z4D-F, otherwise it may explode or burn.
Do not impose 100 VAC on any Z4D-F
model, otherwise it may explode or burn.
Load short-circuit
Do not short-circuit the load, or the Z4D-F
may explode or burn.
Wiring
Be sure to wire the Z4D-F correctly and be
careful not to connect the polarities incor-
rectly, otherwise it may explode or burn.
Connection with no load
If connected to the power supply without
any load, internal elements may explode or
burn. Make sure to connect a proper load to
the Z4D-F.

■Correct Use
Mounting
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 accu-
rate results, it is recommended that the sensing distance is set to
the measurement point (4 mm).
Note: As the optical axis will be adjusted later, temporarily fix the
Sensor.
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 indi-
cator 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.
After the optical axis has been adjusted, tighten the mounting
screws firmly.
Z4D-F04A
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.
Analog Output Diagram
Z4D-F04D
ON/OFF Output Diagram
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.
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.
