Actuators with Battery-less Absolute Encoders

SMC has introduced a line of actuators driven by 24VDC step motors fitted with battery-less absolute encoders.  An absolute encoder offers position data upon power-on, avoiding the homing routine an incremental encoder requires.  Our battery-less absolute encoder pairs orientation sensors with differently sized rotating wheels to enable position detection.  This electro-mechanical design eliminates the battery and its accompanying import and disposal restrictions common to traditional absolute encoders.  A battery-less solution is also free of memory retention limits from extended power-off situations.

LEFS Slider Type, Ball Screw Drive, Battery-less Absolute Encoder
The rodless LEFS slider is an electric actuator with a load mounting platform situated above a ball screw drive.  A flexible seal band permits platform travel while preventing foreign matter from entering the drive.  Slider advantages include a low profile height, shorter length than a rod with equivalent stroke, and better positioning repeatability than a…
LEFB Belt Drive Slider, Battery-less Absolute Encoder
The rodless LEFB slider is an electric actuator with a load mounting platform situated 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, shorter length than a rod with equivalent stroke, plus longer strokes and higher speeds than…
LEY Rod, Battery-less Absolute Encoder
The LEY rod electric actuator is suitable for push, pull, lift and press applications.  The motor orientation can be reverse mounted on top for compact length, or inline for compact height.  Several mounting options are available to accommodate a range of machine requirements.  This version includes a 24VDC motor with a battery-less absolute encoder.  This…
LEYG Guided Rod, Battery-less Absolute Encoder
The LEYG guided rod electric actuator pairs a LEY actuator with a bolt-on bearing block with double guide rods.  The guide rods counter rotational forces instead of the drive and motor, and also resist shock and sustained lateral loads.  Guide selection offers either slide or ball bushing bearings.  The motor orientation can be reverse mounted…
LES Slide Table, Compact, Battery-less Absolute Encoder
The LES electric actuator combines a motor and ball screw drive, worktable, and linear guide in compact body.  The formed sheet metal table allows a lower mounting surface height, lighter weight, and greater vertical work load than the LESH slide table.  Body orientations include basic, symmetrical, and inline mounted motor.  This version includes a 24VDC…
LESH Slide Table, High Rigidity, Battery-less Absolute Encoder
The LESH electric actuator combines a motor and ball screw drive, worktable, and linear guide in compact body.  The machined table is more rigid than the LES formed table, enabling higher horizontal loads and improved deflection from offset loading.  Body orientations include basic, symmetrical, and inline mounted motor.  This version includes a 24VDC motor with…
LEHF Gripper, Battery-less Absolute Encoder
The LEHF gripper uses a belt driven slide shaft to open and close the fingers.  The low profile, flat fingers follow a linear guide for alignment and stability.  The body and drive construction permit long strokes, suitable for gripping larger items without excessive moment loading.  This version includes a 24VDC motor with a battery-less absolute…
LER Rotary Table, Battery-less Absolute Encoder
The LER features a rotating worktable positioned above an enclosure for the motor and drive train.  Both a basic and high torque variation are offered.  Three rotation angles are also available, including 90°, 180°, or 320°.  This version includes a 24VDC motor with a battery-less absolute encoder.  This encoder allows the actuator to be powered down…
LESYH-X171, Electric Slide Table, High Precision Type, Battery-less
The LESYH is a high precision variation of the LESH high rigidity slide table.  This actuator improves positioning repeatability to ± 0.01 and increases vertical work load dramatically compard to the LESH.  The external motor can be mounted inline with the table, or in parallel to the left or right.  This version includes a 24VDC step…
