Precautions for Use
(1) This module is designed to be operated
at I
F
= 30mA TYP.
(2) Fixing torque: MAX. 0.6Nm 6kgf cm
(3) In order to stabilize power supply line,
connect a by-pass capacitor of more than 0.01
μ
F
between Vcc and GND near the device.
(4) As for other general cautions, refer to
the chapter “Precautions for Use” .
