Without need for separate control box, noncontact EZ-Screen requires only self-contained emitter and receiver pair. Because safety light curtain is controlled optically, there is no need for synchronization wire between emitter and receiver, making installation and operation easy. It measures just 45.2 x 36 mm and is available in 2 resolutions. Curtain suits finger or hand detection on smaller production machines, yet is robust enough for large power presses. Self diagnostics help simplify setup.
