ELECTRIC ACTUATOR SMC LEFS SERIES

Sliding electric cylinder/ LEFS . lead screw

Model: LEFS/LEFS40RH-500-S3AN3D/LEFS32RH-500-R3AN3D/LEFS25LH-450-S3AN3D

Restart from the last stop position is possible.
Easy operation restart after recovery of the power supply
　The position information is held by the encoder even when the power supply is
　turned off.
　A return to origin operation is not necessary when the power supply is recovered.
No battery is installed. Reduced maintenance
　No battery is used to store the position information.
　There is no need to manage spare batteries or replacement maintenance.
Max. work load: 65 kg
Positioning repeatability: ±0.015 mm (High precision type)
