Many emerging applications require encoders with extended misalignments between the moving sensor and the static scales. Based on capacitive sensing and differential pattern design, the CAPLINs offer easy to implement solutions for those demands.
The CAPLIN scale, produced with the well-established PCB process, is cost effective while it achieves the accuracy less than tens of micro meters per meter.
Based on a patented coding technology, CAPLIN offers an absolute positioning function at the power-up stage. The addressable length is up to 10 meters.
