Blind Hollow shaft multiturn absolute encoder with spring. Rev 2.0. Encoder size 63 mm.
Industry standard optical rotation angle sensor with hollow shaft blind. RMS resolution up to 27 bits, push-pull or Bit Parallel, SSI conjunction by cable or connector, hollow shaft diameter up to 15 mm. Multiturn optical encoders utilize a power harvesting system built on the Wiegand effect to measure the speed. This system does not need a power supply or batteries.
