■Description
■Agency approvals/Compliance
GP1A057SGKLF is a transmissive photointerrupter
with digital 2 output (phase A/B) encoder function.
Using this with a linear scale (or rotation disk) that
forms a slit pattern, this product detects the movement
(rotation) direction and the amount of movement
(number of revolutions, rotation angle).
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 0.56 [mm]
(45LPI)
5. Package : 12.2×7.4×8.27mm

*1 The test condition is according to Fig.3 (CY14439i06)
And transfer characteristics value does not include any error of code-wheel (Liner scale).
The error of slit-pattern shall not be included.
*2 Z stands for distance between code-wheel (Liner scale) surface (patterned surface) and detector holder surface,
and patterned surface shall be arranged face to face with detector holder surface.
The code-wheel (Liner scale) shall not contact with the holder surface.
Note: It is recommended that the GP1A057SGKLF be used under the condition of typical IF=20mA for which it is
designed.

■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.
●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.
