Light Convergent Reflective Photomicrosensor
EE-SPY31/41
CSM_EE-SPY31_41_DS_E_5_2
Accurately detects objects placed in
front of shiny Background.
• A shiny background can be used as long as the distance between
the sensor and the background is 20 mm or more.
• Detects minute objects such as a 0.05-mm-dia. pure copper wire.
• Small dispersion in sensing distance.
• Light modulation effectively reduces external light interference.
• Wide operating voltage range: 5 to 24 VDC

Safety Precautions
Refer to Warranty and Limitations of Liability.
WARNING
• 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 as shown below.
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.)
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 Correct Use
Make sure that this product is used within the rated ambient
environment conditions.
● Wiring
• Connection is made using a connector. Do not solder to the pins
(leads).

2 m max.
• Make sure the total length of the power cable connected to the
product is less than 10 m even if a capacitor is inserted.

The following are some examples of applications for which particular attention must be given. This is not intended to be an exhaustive list of all possible
uses of the products, nor is it intended to imply that the uses listed may be suitable for the products:
 Outdoor use, uses involving potential chemical contamination or electrical interference, or conditions or uses not described in this catalog.
 Nuclear energy control systems, combustion systems, railroad systems, aviation systems, medical equipment, amusement machines, vehicles,
safety equipment, and installations subject to separate industry or government regulations.
 Systems, machines, and equipment that could present a risk to life or property.
Please know and observe all prohibitions of use applicable to the products.
NEVER USE THE PRODUCTS FOR AN APPLICATION INVOLVING SERIOUS RISK TO LIFE OR PROPERTY WITHOUT ENSURING THAT THE
SYSTEM AS A WHOLE HAS BEEN DESIGNED TO ADDRESS THE RISKS, AND THAT THE OMRON PRODUCTS ARE PROPERLY RATED AND

Disclaimers
CHANGE IN SPECIFICATIONS
Product specifications and accessories may be changed at any time based on improvements and other reasons.
It is our practice to change model numbers when published ratings or features are changed, or when significant construction changes are made.
However, some specifications of the products may be changed without any notice. When in doubt, special model numbers may be assigned to fix or
establish key specifications for your application on your request. Please consult with your OMRON representative at any time to confirm actual
specifications of purchased products.
DIMENSIONS AND WEIGHTS
Dimensions and weights are nominal and are not to be used for manufacturing purposes, even when tolerances are shown.
PERFORMANCE DATA
Performance data given in this catalog is provided as a guide for the user in determining suitability and does not constitute a warranty. It may represent the
result of OMRON’s test conditions, and the users must correlate it to actual application requirements. Actual performance is subject to the OMRON
Warranty and Limitations of Liability.
