True-image technology for reliable feedback of position information does not require sealed air

     Heidenhain enclosed linear gratings and encoders with innovative true-image technology ensure that the gratings signal is not affected by condensation and other liquid contamination on the machine. The Heideham 6 Series LC Linear grating ruler and the 1 Series RCN Angle encoder provide reliable, high-precision position data, even without the need for sealed air in most applications. As a result, system costs and encoder carbon emissions can be reduced by up to 99%.

     The coolant used during the machining of the workpiece by the machine can produce condensate and liquid contamination. Heideham 6 series LC enclosed linear grating ruler and 1 series RCN Angle encoder with built-in bearing provide clear grating measurement signal, which is not affected by pollution. Behind it is innovative true-image technology. Specially designed optical transducers fully eliminate optical deformations of gate lines, such as those caused by grating ruler drops. Grid-line images are directed to the reading head without interference, including in environments with liquid contamination.

     The Heideham 6 Series LC Linear grating ruler and the 1 Series RCN Angle encoder provide reliable, high-precision position data, even without the need for sealed air in most applications. These grating scales and encoders significantly simplify the machine's sealed air system and reduce carbon emissions by up to 99%, thus effectively reducing the total system cost. The optics are reliable against pollution, maintaining high machine productivity and availability even without the use of sealed air. True-image technology reduces the number of parts in the machine's sealed air system, making installation of the grating ruler and encoder easier.
