Absolute Linear Encoders
Absolute Linear Encoders are designed for measuring and checking displacements, dimensions, run-outs, surface profiles and deformations of engineered objects.
Operation of the sensors is based on the principle of photoelectric scanning of special scale, connected with a measurement tip of the sensor. As compared with incremental sensors, absolute sensors have a number of advantages: the absolute position of the gage plug is determined immediately after power is on and the necessity of search of the reference mark is excluded.
Riftek’s absolute encoder series includes two models: The RF251 for hard industrial environments and the RF256 sensors with a built-in display option for laboratory environments.
