The ENI90 series hollow shaft rotary encoders with BlueBeam technology are characterized by high signal quality and maximum precision in rotational speed measurement. Due to the blue light of the BlueBeam technology, the ENI90 series incremental rotary encoders reliably achieve the highest measurement accuracy, even under the toughest conditions. Three device types and a comprehensive range of accessories offer almost unlimited configuration options for a wide variety of applications. They prove their worth wherever high-precision speed control is required, e.g. in crane systems, steel mills, and wind turbine applications. The ENI90IL basic version is the economical solution for all standard applications. The ENI90PL rotary encoder is designed for demanding environments and offers highest shock and vibration resistance. Its insulated shaft is suitable for high dielectric peaks. The EMC protection provides electrical surge immunity for the rotary encoder. For extreme conditions, the ENI90HD heavy-duty version is available. The devices in this series offer even higher dielectric strength for powerful EMC protection and can withstand maximum shaft loads.
