Does anyone make an opto-coupler that would transmit from the end of a rotating shaft with the stationary pick-up in the end housing?

    Have not heard of such an ANALOG opto coupler but I have worked with several digital couplers that can be used to transmit analog data. If you post or PM me your application I might be able to suggest something.

    Yarisboy,
    I once built my own optocoupler using the infared transmitter receiver pair offered by radioshack. It worked fine to transmit motor drive pwm pulses where I wanted to isolate the motor on a seperate power supply from the prop.
