The ENI58IL rotary encoder with BlueBeam technology enables the precision required for rotational speeds of up to 12,000 rpm. This is achieved by implementing a blue emitter LED and the corresponding receiver diodes. When used in conjunction with a powerful sensing chip, it enables an efficient utilization of light. Because the high-frequency sampling is less prone to interference, the technology keeps signals stable when exposed to mechanical forces such as shock and vibration. Code disk calibration also is improved. Interlocked bearings withstand high loads and protect the ball bearing, and special EMC circuit protection prevents damage from electromagnetic interference.
