Safety Precautions
Refer to Warranty and Limitations of Liability.
This product is not designed or rated for ensuring
safety of persons either directly or indirectly.
Do not use it for such purposes
Make sure that this product is used within the rated ambient
environment conditions.
● Mounting
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). Do not place
glossy objects in the background of the sensing object.
● Wiring
•Connection is made using a connector. Do not solder to the pins
(leads).
•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.)
•Make sure the total length of the power cable connected to the
product is less than 10 m even if a capacitor is inserted.
