Mounting a small ultrasonic sensor to a continuous rotation servo

[Jae]

I'm an Arduino electronics hobbyist I'm not a professional electrical engineer.

How would I mount a small ultrasonic sensor on a continuous rotation servo, without tangling the wires? How would I fix this problem easily and what's the most common way to mount electronics in a rotating object?

Thank you for your time.

Rotary transformer might solve your issue.

Or battery power and Bluetooth Low Energy (BLE) to link the data...

Rotary transformers can be found in old VCRs. They coupled the spinning video head to the signal processing section. I wouldn't guess that a single winding would have sufficient magnetizing inductance for your frequency, but many of these had four windings that could be jumped in series for a much lower frequency response.
You might also mount the transducer facing up (or down), and use a reflective shape that is spinning on the servo to direct it sideways.
