Linear encoder without optics
Gurnee, Ill. -Dynapar brand LR/LS Inductive Linear Encoder from Danaher Controls uses inductive sensing technology to combine the speed and resolution of optical linear encoders with the ruggedness and low cost of magnetic linear encoders. These encoders use magneto-resistive sensors that detect minute changes in the variable reluctance of an etched metal tape scale. Electronic circuitry produces low distortion, sine/cosine, or standard quadrature outputs. The system reportedly provides the high speed, high resolution and, high accuracy required for demanding applications such as linear motion feedback, electronics assembly, and printed circuit board fabrication.
