光栅由发射器和接收器单元组成,接收器单元具有大量红外线穿过梁的平行阵列。它们具有二维检测领域,用于监控大面积。In spite of the simple operating principle, you’ll find an array of specialized light grids in our portfolio: large light beam angles ensure easy alignment, “Teach-in” functions permit fast adjustment, crossed light beams increase the resolution of the light grids, and automatic calibration of the signal strength ensures safe operation even in dirty or dusty areas.
