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.
