*1. An inrush current of approximately 2 A will flow for approximately 50 μs when the power is turned ON.
*2. The maximum electrical response speed is determined by the resolution and maximum response frequency as follows:
Maximum response frequency × 60
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.

WARNING Precautions for Correct Use
This product is not designed or rated for ensuring Do not use the Encoder under ambient conditions that exceed the
safety of persons either directly or indirectly. ratings.
Do not use it for such purposes. ● 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.
