What does the “WARNING” signal word mean?
Indicates a potentially hazardous situation which, if not avoided, will result in minor or moderate injury, or may result in serious injury or death. Additionally there may be significant property damage.
What is the primary safety warning for this product?
This product is not designed to be used either directly or indirectly in applications that detect human presence for the purpose of maintaining safety. Do not use this product in sensing devices designed to provide human safety.
What are the precautions for safe use?
Power Supply Voltage
Do not exceed the voltage range indicated in the specifications. Applying a voltage exceeding the specifications or using an AC power supply may result in rupture or burning.
Faulty Wiring
Do not reverse the power supply polarity. Doing so may result in rupture or burning.
Load
Do not short-circuit the load. (Do not connect to the power supply.) Doing so may result in rupture or burning. Be sure to install a protection, such as a fuse (Fusing current 0.1A) on the wiring for the load. The sensor has not the load short protection function.
Disposal
Dispose of this product as industrial waste.
What are the precautions for correct use and installation?
The sensing distance for the EE-SPY Reflective-type Photomicrosensor with built-in amplifier varies from 8 to 20 mm depending on the product (90% reflective white paper). Light reflected from any background object may result in incident light. Consider this factor and make adjustments before using the Sensor.
Mount the Sensors securely on a flat surface.
Mount the Sensor with two M3 screws, using a spring washer to ensure the screws will not become loose. Use a tightening force of 6 kgf·cm (0.59 N·m) max.
What should I know about the power supply?
When a commercially available switching regulator is used, switching noises may cause malfunction. The frame ground and the ground terminals of the switching regulator should be grounded to ensure stable operation of the product.
How should the sensor be wired?
Surge Protection
If there is surge in the power supply, try connecting a capacitor (with a capacitance of 0.1 to 1 µF) or a Zener diode (with a rated voltage of 30 to 35 V). Use the Sensor only after confirming that the surge has been removed.
Driving Inductive Loads
When driving a small inductive load, such as a relay, wire as shown in the manual. Be sure to connect a diode between the OUT and +V terminals to absorb the reverse voltage.
Wiring Separation
Separate the wiring for the Sensor from high-tension lines or power lines. If the wiring is routed in the same conduit or duct as such lines, the Sensor will be damaged or its operation will be affected by inductive interference.
Connectors
Make sure that the connectors (either dedicated or commercially available) are securely locked.
What are the design considerations for extending the cable?
When extending the cable, use an extension cable with conductors having a total cross-section area of 0.3 mm². The total cable length must be 2 m maximum.
To use a cable length longer than 2 m, attach a capacitor with a capacitance of approximately 10 µF to the wires. The distance between the terminal and the capacitor must be within 2 m. Use a capacitor with a dielectric strength that is at least twice the Sensor’s power supply voltage.
What should be done to mitigate the effects of inductive noise?
When there is inductive noise in the Sensor mounting frame (metal), the output of the Sensor may be affected. In this case, ensure that there is no electrical potential difference between the Sensor 0-V terminal and the Sensor mounting frame, or attach a 0.47 µF capacitor between the Sensor’s 0V terminal and the mounting frame.
What other precautions should be taken?
Do not disconnect the Connector from the Sensor when power is supplied to the Sensor, or Sensor damage could result.
Avoid installing the Sensor in the following places to prevent malfunction or trouble:
1. Places exposed to dust
2. Places exposed to corrosive gases
3. Places exposed to water, oil, or chemicals
4. Outdoor or places exposed to intensive light, such as direct sunlight
Be sure to use the Sensor under the rated ambient temperature.
The Sensor may be dissolved by exposure to organic solvents, acids, alkali, or aromatic hydrocarbons, causing deterioration in characteristics. Do not expose the Sensor to such chemicals.

|---|---|---|
| EE-SPX401 EE-SPY401 EE-SPY402 |
Light-ON |
Incident: Light indicator ON, Output transistor ON Interrupted: Light indicator OFF, Output transistor OFF |
| EE-SPX301 EE-SPY301 EE-SPY302 |
Dark-ON |

Output Circuit
The NPN output circuit consists of a main circuit with a light indicator (red) connected between Vcc and the collector of the output transistor. The output (OUT/Load 1 and Load 2/GND) is taken from the collector and emitter of the transistor. The circuit is powered by 5 to 24 VDC. A voltage output can be achieved when the sensor is connected to a transistor circuit.
