Optical triangulation position sensors use reflected waves to pinpoint position and displacement. The source of these waves may be a light emitting diode (LED), infrared (IR) light, or laser.
Position probes measure the position of a target surface, usually with a high degree of accuracy. This search form covers many different linear position products.
Time of flight optical sensors determine displacement and distance by measuring the time it takes light to travel from the instrument to a target and back.
