25A-LEFS Electric Actuator, Ball Screw Slider, AC Servo Motor, Secondary Battery
The 25A- series variations are compatible with secondary battery manufacturing for electronics, automotive, and other vehicle types. Design goals include eliminating copper (Cu) and zinc (Zn) material where possible, and employing a low dew point grease that retains lubricity even in low manufacturing temperatures. Please note that copper and zinc materials are used for the motors, cales, controllers and drivers.
- Same features and performance as standard LEFS AC Servo
- Stainless steel bolts for construction
- Low dew point grease functional down to -70°C
- Copper and zinc free except for motor, cables, and driver
- Non-standard materials for compatibility with secondary/rechargeable battery manufacturing

Caution
[CE-compliant products]
q EMC compliance was tested by combining the electric actuator LEF series and the controller
LEC series.
The EMC depends on the configuration of the customer’s control panel and the relationship
with other electrical equipment and wiring. Therefore, conformity to the EMC directive cannot
be certified for SMC components incorporated into the customer’s equipment under actual
operating conditions. As a result, it is necessary for the customer to verify conformity to the
EMC directive for the machinery and equipment as a whole.
w For the servo motor (24 VDC) specification, EMC compliance was tested by installing a noise
filter set (LEC-NFA).
Refer to page 568 for the noise filter set. Refer to the LECA Operation Manual for installation.
e CC-Link direct input type (LECPMJ) is not CE-compliant.
[UL-compliant products]
When conformity to UL is required, the electric actuator and controller/driver should be used with a
UL1310 Class 2 power supply.
Series compatible with
secondary batteries
The actuator and controller/driver are sold as a package.
Confirm that the combination of the controller/driver and the actuator is correct.
<Check the following before use.>
q
Check the actuator label for model number (after "25A-"). This matches the controller/driver.
w Check Parallel I/O configuration matches (NPN or PNP).
* Refer to the operation manual for using the products. Please download it via our website, http://www.smcworld.com
