The ACT Print Mark Sensor offers maintenance free solid state reliability, with the sensing performance until now offered only by short-lived incandescent color mark sensors. The ACT reliably detect all color contrasts found in common product registration color mark applications – even such extremely low contrasts as 35 percent yellow printed on white. In addition, single colour LED light source 35 microsecond sensing response produces excellent registration repeatability, even in ultra-high-speed applications. This fast response, coupled with the small 10 x 3 mm sensing image, allows color marks to be made small and inconspicuous.

The NTC-727 reliably detects all color contrasts found in common product registration color mark applications – even such extremely low contrasts as 20 percent yellow printed on white. In addition, three colour LED light source and hybrid optics eliminate the need to switch between different color light sources for different color contrasts. 25 microsecond sensing response produces excellent registration repeatability, even in ultra-high-speed applications. This fast response, coupled with the small 10 x 3 mm sensing image, allows color marks to be made small and inconspicuous.
