Absolute encoders are singleturn / BiSS C that is used for integration with Optical sensing method and also they are made in Germany . Some of the absolute encoders are :
The EAM580R is one of Bumer's absolute encoders, known for its high accuracy and resistance to environmental factors such as dust and moisture. This encoder is especially used in harsh environments and sensitive applications such as heavy machinery and drilling equipment.
Very high accuracy with resolution up to 16 bits
Resistant to shock and vibration
Multiple communication protocols such as PROFINET and EtherCAT
