forms a slit pattern, this product detects the movement
(rotation) direction and the amount of movement
(number of revolutions, rotation angle).
This product has mounting holes for screwing to a
substrate.
1. Compliant with RoHS directive (2002/95/EC)
■Applications
1. Detects direction of movement, the amount of
movement, rotation angle of equipment and device
that move horizontally or rotate.
Example : printer, copier, robot, motor control, etc.
■Features
1. Transmissive Photointerrupter
2. Case type, with encoder function
3. Output signal : Digital 2 output (A Phase / B Phase)
4. Resolution : Linear scale slit pitch 0.0847 [mm]

■Notes
●The recommendation conditions of forward current:
This product is designed in consideration of using this product under the condition of typical IF=20mA as a standard.
●In order to stabilize power supply line, it is recommended to have a by-pass capacitor of 0.1μF or more
between Vcc and GND near the device.
●Lens is made from resin, as to cleaning, this photointerrupter should not be cleaned by cleaning materials
absolutely. (Dust and stain shall be cleaned by air blow.)
●Soldering
To solder onto lead pins, please solder at 260°C for 5s or less with longer distance than 1.6mm from the bottom
surface of the package.
Please take care not to let any external force exert on lead pins when soldering or just after soldering.
Please don't do soldering by reflow.
●OPIC chip due to micro design is easily affected by the Electro static discharge.
At operating, in order to prevent the destruction and the defect of characteristics by Electro static discharge,
please take a general countermeasure of the Electro static discharge.
●Prevention of malfunction
For this product, the transparent material is used as the case material .
Before using this product, please confirm the following items with the actual equipment.
1) The product does not malfunction by the ambient light illuminating the photo-detector surface.
2) Other equipment is not affected by the light leaking from the light-emitting device.
●Assembly of the device
When tightening this product with the screw, please use the M2.6 machine screw. The recommended tightening torque
with M2.6 machine screw is 0.25 to 0.35 N・m.
However, this recommended tightening torque is the reference value because the tightening torque varies according to
the screw and the bolted joint.
Before tightening the screw, please certainly confirm the tightening strength of this product and the object on which this
product is mounted
Also, when tightening the screw with the tools such as the screw-driver, if the pushing force by the screw-driver is too
strong, the damage of the product performances such as the break of the holder’s mounting hole may be caused by the
application of the external force. Therefore, please be careful not to apply such a force to this product.
●Storage and usage environment
Polycarbonate is used as the case material of this product.
If polycarbonate contacts with the hot liquid and the alkaline solution (alkaline atmosphere),
polycarbonate is hydrolyzed. Therefore, please do not store and use this product in such an environment.
