Mercedes only uses selected components. Especially for their motor test rigs, they require the best and most accurate sensors. In this high-speed application with lots of vibration, GES encoders are the perfect choice.
Especially since all incremental encoders are manufactured with an optical disk made of synthetic material. This ensures that it will last and not break as a result of the vibration and/or shock during this heavy duty application.
Encoder IS581 is the perfect choice. It is available in various shaft sizes and with cable exit or various connectors.
