Encoders are sensors that generate digital signals in response to movement. Encoders come with two outlines: rotary and linear. Both types sense mechanical motion and translate the information (velocity, position, acceleration) into useful data.
A contactless technology
To address demands for longer service life and with its strong track record in contact technology position sensors (potentiometers), Electromechanical Solutions SBU has been developing own-brand contactless sensors for nearly 10 years. These sensors are absolute and incremental optical encoders, magnetic technology and inductive sensors.
Absolute optical or magnetic encoders: absolute optical encoders are position sensors that use optical signals to identify an absolute angular position. The Exxelia encoders offer very high performance levels for a very small footprint:
- high precision (<30 arcsec),
- high resolution (up to 21 bits),
- highly thin (10mm),
- EMI EMC compatibility
Incremental optical or magnetic encoders: absolute optical encoders are position sensors that use optical signals to identify an absolute angular position. Incremental encoders have to be initialized by a first turn to produce an absolute position.
Applications: Aeronautics, Defense, Railway, Medical, Oil exploration, Telecommunications
Exxelia encoders can also be easily combined with other functions like Slip rings or rotary joints (FORJ, HF...) in complete proprietary systems.
