  • Page 6: Safety

    Intended Use The ENI11HD incremental rotary encoder is used to record rotations though a direct mechani- cal coupling with a rotating drive shaft. Internally, the rotation is converted into a sequence of electrical pulses which are provided by the rotary encoder on several output channels. With its robust design, the rotary encoder is particularly suitable for applications in which strong exter- nal mechanical loads can affect the rotary encoder.
