Incremental encoders
Incremental encoders generate information about position, angle, and rotation counts. The resolution is defined in the number of lines or pulses per rotation, which the encoder transmits to the control unit for each rotation. The current position can be determined by the control unit by counting these pulses. A reference run can be necessary when switching on the machine.
Absolute encoders
Flexible, compact and reliable - absolute encoders made to measure!
Absolute encoders generate information about position, angle, and rotation counts in type-specific angle steps. For this, a unique code pattern is assigned to each angle increment. The number of code patterns available per revolution determines the resolution. Each code pattern forms a unique reference, and is therefore an absolute position. There is therefore no need for a reference run after switching on. A singleturn encoder measures the absolute position within a revolution. A multiturn encoder not only provides the position within a revolution but also the number of revolutions.
Bearingless encoders
Bearingless encoders contactlessly generate information about angle, position and speed. The magnetic measurement principle makes it possible to mechanically separate the sensor unit and measuring elements. The bearingless design allows wear-free operation. The flexible mounting options and easy system integration enable it to be used in numerous applications and industries.
