Moving Head Projectors

Moving head projectors are more and more used in theatres and shows. These devices must be resistant and extremely flexible, and able to solve all kinds of problems faced by lighting engineers daily. For this reason, these projectors are equipped with a wide range of motors to maneuver them when quiet, smooth, and high-speed movements, such as the ones of tilt, pan, and focus, are required. It is necessary to run the cables through the pan movement to control the different motors and sensors. Consequently, the cables get twisted, and the functionality is therefore affected. To avoid either cable damage or rupture, it is necessary to use an Electric Rotary Joint (also known as Slip Ring) on the pan axis. In cases where it may be necessary to have more than one turn in both directions to make the moving head projector more flexible, Slip Rings become mandatory.
