Safety Precautions

To ensure safe operation, be sure to read and follow the Instruction Manual provided with the sensor.

WARNING

This product cannot be used as a safety device for
press machines or for protecting the safety of
persons. This product is designed for use in
applications for sensing workpieces and workers
that do not affect safety.

CAUTION

This product is not designed or rated for ensuring
safety of persons either directly or indirectly.
Do not use it for such purposes.

Precautions for Safe Use

Be sure to observe the following precautions to ensure safety.

Wiring

Power Supply Voltage

Do not exceed the operating voltage and current ranges. Applying a
voltage or current exceeding the operating range or using an AC
power supply for the DC power supply sensor may result in rupture or
burning.

Connection without a Load

If the power supply is connected directly without a load, the internal
elements may explode or burn. Be sure to insert a load when
connecting the power supply.

AND Connection

With an AND connection as shown in the figure below, a voltage is
applied to Vcc while GND of sensor 2 is not securely grounded. A
failure may occur. Do not make this kind of connection. Also in some
models, an inrush current may occur in sensor 2 when sensor 1 is
turned on, causing failure or malfunction.

Load Short-circuit

Do not short-circuit the load. Doing so may result in rupture or
burning.

Faulty Wiring

Do not make a mistake with the wiring, such as reversing the power
supply polarity. Doing so may result in rupture or burning.

Typical example 1) Wrong polarity

Storage and Operating Environment

1. Places where the product is not exposed to corrosive gases, such

as hydrogen sulfide gas, or salty wind.

2. Places where it is not exposed to direct sunlight.

3. Make sure that flux, oil, or other chemicals do not adhere to the

surface of the emitter and receiver.

4. Do not apply a load that may deform or deteriorate the product in

any circumstances.

5. Store the product in a normal temperature, humidity, and pressure

environment.

6. The product should be used without freezing or condensation.

7. Do not use the product in atmospheres or environments that

exceed product ratings.

8. This product does not have a water-proof or dust-proof structure.

Therefore, do not use it in an application or environment where it
will be subjected to dust or splashes from water, oil, or any other
liquid.

Mounting

1. This product is intended to be built into devices so no special

measures have been taken against external light interference.
When using a DC light sensor in an area exposed to an
incandescent lamp or other external light interference, it should be
mounted so that the effects of external light interference can be
avoided.

2. Mount the sensor securely on a flat surface.

3. Use M3 screws to secure the Photomicro Sensor (use together

with spring washers and 6-mm-diameter flat washers to prevent
screws from loosening). Use a tightening torque of 0.54 N·m max.

4. Take care that nothing comes into contact with the sensing

element of the sensor. Damage to the sensing element will result
in poor performance.

5. Before using the sensor, check to make sure that it has not

become loose due to vibration or shock.

Wiring

Surge Prevention

1. If there is a surge in the power supply, try connecting a Zener

diode (ZD with a voltage of 30 to 35 V) or a capacitor (with a
capacitance of 0.1 to 1 µF), depending on the operating
environment. Use the sensor only after confirming that the surge
has been removed.

EE-SX3173/4173-P Series

Voltage Output

A sensor with an open collector output can be connected to a counter
with a voltage input by connecting a resistor between the power
supply and output. Select a resistor with reference to the following
example. The resistance of the resistor is normally 4.7 kΩ. The
wattage of the resistor is 0.5 W at a power supply voltage of 24 V.

3. If photomicrosensor wires are placed in the same tubes or ducts

as high-voltage lines or power lines, induction may cause
malfunction or damage. Either wire the photomicrosensor
separately or place the wires in separate tubes.

4. Make sure that connectors (commercially available) are securely

locked.

Handling during Wiring

1. If a force is applied to the connection area between the terminal

and connector by bending or pulling the cable after the wiring is
completed, the connector contact part or connection area with the
cable may be damaged, resulting in contact failure. Make sure that
a stress (external force) as shown in the figure below is not applied
to the connection area between the terminal and connector when
routing and connecting cables or harnesses.

2. Do not perform cord wiring when power supply voltage is applied.

Doing so may result in damage.

Other Precautions

Make sure the total length of the power cable connected to the
product is less than 10 m.

Design

Design should be made so that light is completely shut off during
operation. We recommend that sensing objects are made of metal.
(With an infrared light sensor, infrared light will pass through the
sensing object made of resin, resulting in unstable detection.)

Connection with PLC (NPN Open Collector Type)

Mounting should be carried out by reference to the figure below.

Others

1. Do not connect or disconnect the connector while power is

applied. Doing so may result in breakage.

2. Do not mount the sensor in the following places because doing so

may cause malfunction or damage.

1) Places exposed to dust or oil mist

2) Places exposed to corrosive gas

3) Places directly or indirectly exposed to water, oil, or chemicals

4) Outdoor or places exposed to intensive light, such as direct
sunlight

5) Make sure that the operating ambient temperature is within the
rated range.

3. The sensor may be dissolved by exposure to organic solvents,

acid, alkali, aromatic hydrocarbon, and chlorinated aliphatic
hydrocarbon solvents, causing deterioration in the characteristics.
Do not expose the sensor to such chemicals.

4. An output pulse may occur when the power supply is turned ON

depending on the power supply and other conditions. Use the
sensor in the stable ready-for-detection state reached in 100 ms
after turning on the power supply.

Connection with Counter (NPN Open Collector Type)

Mounting should be carried out by reference to the figure below.
