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 [Insert Product Name] is a high-speed, precision sensor designed for accurate detection of print, color, or registration marks on a wide range of materials including paper, film, foil, plastic, and transparent substrates. Featuring RGB LED illumination with automatic color selection, it eliminates the need for manual light adjustments and ensures consistent detection across various background conditions.

With an ultra-fast response time of ≤ 25 microseconds, this sensor supports up to 20,000 detections per second, making it ideal for high-speed printing, packaging, labeling, and converting applications. Its compact sensing image (1.2 mm x 3.8 mm) allows for precise registration even on small or subtle color marks.

The sensor offers dual digital outputs (PNP & NPN, NO/NC configurable), ensuring seamless compatibility with modern automation systems and PLCs. Teach-in calibration buttons simplify the setup process, while LED indicators provide clear visual feedback for power, alignment, and mark detection.

Encased in a robust, IP65-rated aluminium-zinc alloy housing, the sensor is built to withstand dust, vibration, and harsh industrial environments, offering maintenance-free performance for years of continuous operation.

The NTC-727  Color Mark Sensor offers maintenance-free solid- statereliability, with the sensing performance until now offered only by short-lived incandescent color mark sensors. 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.
