LE Series Electric Actuators with Absolute Encoder

LE Series Electric Actuators
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.
LEFS Slider Type, Ball Screw Drive, Battery-less Absolute Encoder

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 belt driven slider. This version includes a 24VDC motor with a battery-less absolute encoder. This encoder allows the actuator to be powered down without losing its positional awareness. The machine’s PLC can access the controller’s operational and positional step data through several fieldbus protocols, IO-Link, or parallel I/O.

  • Body sizes: 25, 32, 40
  • Maximum work load: 65 kg
  • Maximum speed: 1200 mm/s
  • Stroke range: 50 to 1200mm in 50mm increments
  • Positioning repeatability: ±0.02mm, or ±0.015mm (high precision)

LEFB Belt Drive Slider, Battery-less Absolute Encoder

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 a ball screw driven slider. This version includes a 24VDC motor with a battery-less absolute encoder. This encoder allows the actuator to be powered down without losing its positional awareness. The machine’s PLC can access the controller’s operational and positional step data through several fieldbus protocols, IO-Link, or parallel I/O.

  • Body sizes: 16, 25, 32
  • Maximum work load (horizontal only): 19 kg
  • Maximum speed: 1500 mm/s
  • Stroke range: 300 to 2000mm in 100mm increments
  • Positioning repeatability: ±0.08mm

LEY Rod, Battery-less Absolute Encoder

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 encoder allows the actuator to be powered down without losing its positional awareness. The machine’s PLC can access the controller’s operational and positional step data through several fieldbus protocols, IO-Link, or parallel I/O.

  • Body sizes: 16, 25, 32, 40
  • Maximum work load: 90 kg (horizontal); 53 kg (vertical)
  • Maximum pushing force: 1058 N
  • Maximum speed 500 mm/s
  • Maximum stroke: 500mm
  • Positioning repeatability: ±0.02mm

LEYG Guided Rod, Battery-less Absolute Encoder

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 on top for compact length, or inline for compact height. This version includes a 24VDC motor with a battery-less absolute encoder. This encoder allows the actuator to be powered down without losing its positional awareness. The machine’s PLC can access the controller’s operational and positional step data through several fieldbus protocols, IO-Link, or parallel I/O.

  • Body sizes: 16, 25, 32, 40
  • Maximum work load: 90 kg (horizontal; 51 kg (vertical)
  • Maximum pushing force: 1058 N
  • Maximum speed: 500 mm/s
  • Maximum stroke: 300mm
  • Positioning repeatability: ±0.02mm

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 motor with a battery-less absolute encoder. This encoder allows the actuator to be powered down without losing its positional awareness. The machine’s PLC can access the controller’s operational and positional step data through several fieldbus protocols, IO-Link, or parallel I/O.

  • Body size: 25
  • Maximum work load: 5 kg (horizontal or vertical)
  • Maximum pushing force: 180 N
  • Maximum speed: 400 mm/s
  • Strokes: 30, 50, 75, 100, 125, 150mm
  • Positioning repeatability: ±0.05mm
