Optical scale series KD
The linear optical readers series KD are accurate and reliable, especially suited for applications in severe industrial environments.
They can be profitably employed on machine tools (CNC, boring machines, planomillers, vertical lathes, punching machines…..) and on operating and automatic machines (eg. bending presses, cutting machines, beading machines).
Different reading resolutions are at disposal: 0.1, 0.01, 0.005 or 0.001 mm.
The measuring strokes range from 250 to 6500 mm in compact size, over 6500 in the modular version.
