This motorized transport can be used via IR remote control or 12v trigger to move your Panamorph lens in and out of your projector's light path. The 12v "trigger in" can be connected directly to the "trigger out" of your projector to automatically activate lens movement when the projector's aspect ratio changes when watching TV or widescreen movies. Stress tested design to withstand in excess of 2 million trip, with 18 month warranty. No lubrication required. Designed for use with an attachment kit and RPA mounting kit.
