LEFB, Electric Actuator, Belt Slider, AC Servo Motor
The LEFB slider features a load mounting platform above a belt drive. A flexible seal band permits platform travel while preventing foreign matter from entering the drive. Slider advantages include a low profile height and shorter length than a rod with equivalent stroke. Belt drives allow longer strokes and higher speeds than ball screw drives. The LEFB motor can be top or bottom mounted. This model is fitted with an AC servo motor with incremental or absolute encoder. Optional drivers include pulse input and various communication protocols including Ethernet.
- Body sizes: 25, 32, 40
- Maximum work load: 25 kg
- Maximum speed: 2000 mm/s
- Stroke range: 300 to 3000mm in 100mm increments
- Positioning repeatability: ±0.06 mm
- Encoder resolution: 17-bit (S motors), 22-bit (T motors), 20-bit (V motors)

Confirm that the combination of the controller/driver and the actuator is correct.
The actuator and controller/driver are sold as a package.
<Check the following before use.>
: Check the actuator label for model number. This matches the controller/driver.
@ Check Parallel I/O configuration matches (NPN or PNP).

[CE-compliant products]
: 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.
@ For the servo motor (24 VDC) specification, EMC compliance was tested by installing a noise
filter set (LEC-NFA). Refer to page 44 for the noise filter set. Refer to the LECA Operation
Manual for installation.
[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.
