The Pepperl+Fuchs DK20 Print Mark Sensor is a high-speed contrast sensor designed for precise detection of printed marks in industrial applications. This sensor is particularly suitable for high-speed scanning processes, such as in packaging lines, printing presses, and automated inspection systems.

The Pepperl+Fuchs DK20-9,5/110/124 is a highly specialized and robust print mark contrast sensor, engineered for demanding industrial automation applications where precise detection of contrasting marks on various materials is paramount. Operating as a diffuse mode sensor, it utilizes an advanced RGB light source (Red, Green, and Blue LEDs) to emit modulated light and detect reflections, enabling it to accurately differentiate between print marks and background surfaces regardless of their color, a crucial feature for diverse production environments. A key operational advantage is its static teach-in function, which allows for effortless and automatic adaptation of the switching threshold; users simply present the mark and the background, and the sensor self-calibrates for optimal performance. This sensor is exceptionally fast, boasting a rapid 30 µs response time and a high switching frequency of 16.5 kHz, making it an ideal solution for high-speed production lines common in packaging, printing, and pharmaceutical industries where even milliseconds can impact efficiency and quality. Connectivity is flexible with a push-pull output providing both NPN and PNP signals, complemented by integrated short-circuit and reverse polarity protection, all typically connected via a 5-pin M12 plug. Housed in a durable, IP67-rated glass-fiber-reinforced PC (Makrolon) enclosure with an M5 metal-reinforced insert and a high-grade glass optical face, the sensor is built to withstand harsh industrial conditions. Further enhancing its adaptability, the optical system can be rotated by 90 degrees, offering flexible mounting options for various orientations. Visual feedback is provided by a yellow LED, clearly indicating switching operation, the teach-in process, and any alarm conditions, ensuring operators can quickly monitor its status. With an operating voltage range of 10-30 V DC and a sensing range of 9.5 mm ± 3 mm, the DK20-9,5/110/124 stands out as a reliable and high-performance solution for critical tasks such as registration mark detection, print quality control, and material differentiation across numerous industrial sectors.
