Instruction manual
*1. An inrush current of approximately 6 A will flow
for approximately 0.8 ms when the power is
turned ON.
*2. The code is as follows:
*3. The maximum electrical response speed is
determined by the resolution and maximum
response frequency as follows:

Maximum electrical response speed (rpm) =
× 60
This means that the Rotary Encoder will not operate electrically if its speed exceeds the maximum
electrical response speed.
*4. For the E6C3-AN1E and E6C3-AN2E, the rotation direction input (wire color: pink) can be connected to
high (Vcc) to increase the output code for CW
rotation and connected to low (0 V) to
decrease the output code for CW rotation.
E6C3-AN1E: High = 1.5 to 5 V, Low = 0 to 0.8
V
E6C3-AN2E: High = 2.2 to 12 V, Low = 0 to

or E6C3-AN2E.
*5. The minimum address of the absolute code is
output when cut face D on the shaft and the
cable connection direction are as shown in the
diagram at the right (output position range:
±15°).
