Ratings and Specifications

*1. An inrush current of approximately 9 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:

This means that the E6A2-C Rotary Encoder will not operate electrically if its speed exceeds the maximum electrical response speed.

*3. No protection is provided against water or oil.

Safety Precautions

Refer to Warranty and Limitations of Liability.

This product is not designed or rated for ensuring

safety of persons either directly or indirectly.

Do not use it for such purposes.

Do not use the Encoder under ambient conditions that exceed the

ratings.

● 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.
