Optical incremental linear encoder
120 - 1020 mm, 20 µm | Model BE163C JSC "Precizika Metrology"

The linear encoder is used to convert linear displacements of machine key components into electrical signals containing information about the value and direction of the displacement. Common applications include coordinate and precision machine tools, coordinate measuring machines, microscopes and other high precision equipment.
The system consists of an exposed scale and an encoder read head that works on the transmitted light principle. The scanning portion of the head self-aligns with the scale and thus maintains a constant gap between scanning unit and scale. The glass scale has a grating with two line tracks. One track is the periodic graduation with a constant line pitch of 20 µm. The second contains a reference mark, which can be located 40 mm from either end, from both ends, or in the middle of the measurement range. Unique location of reference marks can also be supplied upon request.
