Light Convergent Reflective Photomicrosensor
EE-SPY31/41
CSM_EE-SPY31_41_DS_E_5_3
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

Note: Refer to Accessories for details.
* EE-1009- or EE-1010-series Connectors have a builtin locking mechanism to prevent cable disconnection when only the cable is pulled. To remove the Connector
from the Sensor, grip the top and bottom of the Connector firmly and push into the Sensor once before pulling out. The locking mechanism prevents the Connector
from being removed by pulling on the cable only and enables removal only when the Connector (housing) is pulled.

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).

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