Tips: Miniature Slip Ring Installation
- Place the cap of the miniature slip ring on the bushing of the instrument to be installed.
- Fix the miniature slip ring rotor part. The miniature slip ring has very low torque, so the rotor does not need to be fixed. Just wire the wires.
- Fix the miniature slip ring stator part. Tighten the screws on the flange of the slip ring so that the cap of the slip ring is attached to the device and remains fixed at all times.

Miniature slip ring with quite compact size of 12.5mm outer diameter, can transmit current and electrical signal in 360° rotation. Current/signal transmission can select 2~18 circuits, max current can be up to 60A/wire. Signals that can be transmitted include Ethernet, video, USB, HDMI, fiber, RF, etc.
