Draw wire encoders offer lers. The Kbler also provides an extensive proven cost-effective solutions in such range of displays, counters and controllers.. applications. Linear motion is converted to rotary motion using a wire that is drawn out Compact or in from the draw wire mechanism. This Measuring length up to 2000 mm rotation is converted into corresponding Robust construction electrical signals by an encoder or poten- tiometer connected to the mechanism.
