*1. An inrush current of approximately 9 A will flow for approximately 0.3 ms when the power is turned ON.
*2. 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
equivalent to AM26LS31.
*3. 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) =
Resolution
This means that the E6B2-C Rotary Encoder will not operate electrically if its speed exceeds the maximum electrical response speed.

Safety Precautions
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 Safe Use
Incorrect wiring may damage internal circuits.
Precautions for Correct Use
Do not use the Encoder under ambient conditions that exceed the
ratings.
● Mounting
• Origin Indication
It is easy to adjust the position of phase Z with the origin indication
function. The following illustration shows the relationship between
phase Z and the origin. Set cut face D to the phase Z origin as
shown in the illustration.

• Do not extend the length of the cable to more than 2 m. If the cable
must be more than 2 m, use a Model with a Line-driver Output
(max. length: 100 m).
● 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.
