Note 1) Distance between disk surface and case surface in the detector side is 0.3mm.
2) Encoder positioning pin is positioned on X-X' axis.
Distance between center of disk and portion A of positioning pin is 12.86mm.
3 ) Center of disk slit is R14.0.
s Precautions for Use
( 1) This module is designed to be operated at I _F= 30mA TYP.
( 2 ) Fixing torque : MAX. 0.6N • m
( 3) In order to stabilize power supply line, connect a by-pass capacitor of more than 0.01 µF
between Vcc and GND near the device.
( 4) As for other general cautions, refer to the chapter “ Precautions for Use” .
