Innovative automation products provides optical incremental linear encoders which have been designed for long life in all medium to high performance applications. The compact bearing type le - 1820 supplies measuring lengths up to 520 mm; the bearing type le - 2534 linear encoders measures up to 920 mm and the more robust and heavy duty bearing type le - 3043 linear encoders have a maximum measuring length of 3.0 metres. All models have a reliable internal circuitry to provide a resolution as fine as 0.5µm after 4x quadrature decode in the user`s circuitry. Precision ball bearings of this linear encoders allow the reading head to traverse the glass scale at speeds up to 1 m/s. The system is protected to ip53 by an aluminum extrusion and rubber sealing flaps.
