RC Model Specifications

RC sensors have a positive rising slope with increasing displacement. Unlike the D models, they are single valued without the near side/far side/optical peak regions and do not need to be calibrated to the target surface. These sensors are suitable for measurement applications involving static, moving or rotating targets, or for in-process parts gaging.
