3. The connector size of the motor cable is different
from that of the electric actuator with an incremental
encoder.
The motor cable connector of an electric actuator with a
battery-less absolute encoder is different from that of an
electric actuator with an incremental encoder. As the connector
cover dimensions are different, take the dimensions below into
consideration during the design process.

Be sure to read this before handling the products. Refer to the back cover for safety
instructions. For electric actuator precautions, refer to the “Handling Precautions for SMC
Products” and the “Operation Manual” on the SMC website: https://www.smcworld.com

When lining up actuators
SMC actuators can be used with their motors adjacent to each
other. However, for actuators with a built-in auto switch magnet,
maintain a space of 40 mm or more between the motors and
the position where the magnet passes.
For the LEF series, the magnet is in the middle of the table, and
for the LEY series, the magnet is in the piston portion. (For other
actuators, refer to the construction drawings in the catalog.)
Can be used with their motors
adjacent to each other
Do not allow the motors to be in close proximity
to the position where the magnet passes.
1. Absolute encoder ID mismatch error at the first
connection
In the following cases, an “ID mismatch error” alarm occurs
after the power is turned ON. Perform a return to origin
operation after resetting the alarm before use.
· When an electric actuator is connected and the power is
turned ON for the first time after purchase
∗
1
· When the actuator or motor is replaced
· When the controller is replaced
∗
1 If you have purchased an electric actuator and controller with the
set part number, the pairing may have already been completed
and the alarm may not be generated.
“ID mismatch error”
Operation is enabled by matching the encoder ID on the
electric actuator side with the ID registered in the controller.
This alarm occurs when the encoder ID is different from the
registered contents of the controller. By resetting this alarm,
the encoder ID is registered (paired) to the controller again.
2. In environments where strong magnetic fields are
present, use may be limited.
A magnetic sensor is used in the encoder. Therefore, if the
actuator motor is used in an environment where strong
magnetic fields are present, malfunction or failure may occur.
Do not expose the actuator motor to magnetic fields with a
magnetic flux density of 1 mT or more.
When installing an electric actuator and an air cylinder with an
auto switch (e.g. CDQ2 series) or multiple electric actuators
side by side, maintain a space of 40 mm or more around the
motor. Refer to the construction drawing of the actuator motor.
The ID number is automatically checked when the
control power supply is turned ON.
An error is output if the ID number does not match.
