Angle Adjuster
Caution
1. Since the maximum angle of the rotation adjustment range
will be limited by the rotation of the rotary actuator itself,
make sure to take this into consideration when ordering.
(Refer to the table below.)

∗1 The maximum adjustment angle of the angle adjuster for size 10 and
40 is 230°.
2. Connection ports are side ports only.
3. The allowable kinetic energy is the same as the
specifications of the rotary actuator by itself (i.e., without
angle adjuster).
4. Use a 100° rotary actuator if you desire to adjust the angle
to 90° using a double vane type.

Be sure to read before handling. Refer to front matters

Rotary Actuator and Auto Switch Precautions.
Caution
1. Since the maximum angle of the rotation adjustment range
will be limited by the rotation of the rotary actuator itself,
make sure to take this into consideration when ordering.

∗1 The maximum adjustment angle of the angle adjuster for size 10 and
40 is 230°.
2. Connection ports are side ports only.
3. The allowable kinetic energy is the same as the
specifications of the rotary actuator by itself (i.e., without
angle adjuster).
4. Use a 100° rotary actuator if you desire to adjust the angle
to 90° using a double vane type.
