LEKFS*E High Rigidity Slider, Ball Screw Drive, Battery-less Absolute Encoder

The rodless LEKFS*E 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.  LEKFS*E includes a redesigned guide with 4 rows of steel balls instead of 2, improving both allowable moment rigidity and positioning repeatability.  Additional enhancements vs. the LEFS include auto switch mounting grooves, improved dustproof performance with magnetic seal band adhesion, standard positioning pin holes and drop-in upgrade replacement vs. LEFS.  The LEKFS*E also features 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
