*1. An inrush current of approximately 6 A will flow for approximately 0.3 ms when the power is turned ON.
*2. The maximum electrical response speed is determined by the resolution and maximum response frequency as follows:
Maximum electrical response speed (rpm) =
This means that the Rotary Encoder will not operate electrically if its speed exceeds the maximum electrical response speed.
*3. No protection is provided against water or oil.
*4. The line driver output is a data transmission circuit compatible with RS-422A and long-distance transmission is possible with a twisted-pair cable. The quality is
Note: Normally connect GND to 0 V or to an external ground.

Safety Precautions
C
Refer to Warranty and Limitations of Liability.
WARNING
This product is not designed or rated for ensuring
safety of persons either directly or indirectly.
Do not use it for such purposes.
Precautions for Correct Use
Do not use the Encoder under ambient conditions that exceed the
ratings.
● Mounting
• The diameter of the mating shaft must be 8 mm and 8 to
11 mm long from the mounting surface.
• The allowable displacement in the mating shaft must 0.05 mm in
the radial direction and 0.3 mm in the thrust direction.
• The mounting surface and shaft must be perpendicular to within
0.03 mm.
WWW.100Y.COM.TWWWW.100Y.COM.TWWWW.100Y.COM.TW
• When securing the Encoder, do not allow force to be applied to the
WWW.100Y.COM.TWWWW.100Y.COM.TWWWW.100Y.COM.TW
leaf spring.

Eccentricity will develop in the
Encoder if the above values are not
satisfied, and the mounting leaf spring
may be destroyed.
WWW.100Y.COM.TWWWW.100Y.COM.TWWWW.100Y.COM.TW
• When securing the Encoder, use two M3 screws to secure the leaf
spring to the mounting surface.
• Use the Allen set screw provided with the hollow shaft to secure the
shaft. Use a tightening torque of 0.4 N·m and apply screw lock glue
to the screw to prevent it from becoming loose.
• If wiring after securing the Encoder, do not pull on the cable. Also,
do not apply shock to the Encoder or hollow shaft.
• If the Encoder phase Z must be aligned with the origin of the
installation device, mount the Encoder while checking the phase Z
output.
● Wiring
Spurious pulses may be generated when power is turned ON and
OFF. Wait at least 0.1 s after turning ON the power to the Encoder
before using the connected device, and stop using the connected
device at least 0.1 s before turning OFF the power to the Encoder.
Also, turn ON the power to the load only after turning ON the power
to the Encoder.
