The sealed linear encoder is used to convert linear displacements of machine key components into electrical signals containing information about the value and direction of the displacement.
The encoder consists of a glass grating scale installed into a rigid hollow housing and a ball-bearing-guided reading head. To be able to work in harsh environments such as lubricants and chips, the encoder has sealing lips. Filtered air can be supplied into the housing of the encoder for extra protection.

Absolute Linear Encoders, RF25X Series
Application domain
Absolute encoders are designed for measuring and checking of displacements, dimensions, runouts, surface profiles and deformations of technological objects.
Operating principle
Operation of the sensors is based on the principle of photoelectric scanning of special scale, connected with a measurement tip of the sensor. Radiation of a LED is collimated by a lens and is directed on a scale. The image of area of the scale is examined by CMOS array and is analyzed by signal processor which calculates position of the scale.
