Precise Contrast Detection
The LEUZE KRTW 3B/2.1121 - S8 is a top - notch contrast sensor designed for accurate detection of minimal contrasts. Operating within a range of 0.0125 - 0.0165 m, it uses a white LED light source. The vertical and rectangular light spot, sized 1.5 mm x 4 mm, enables precise identification of grayscale values. This makes it ideal for applications such as detecting text, imprints, or marks. In industries like packaging, where labels with fine details need to be recognized, the KRTW 3B/2.1121 - S8 ensures high - precision detection, enhancing the overall quality control process.
Reliable Electrical Performance
Electronically, this sensor stands out. It runs on a supply voltage of 10 - 30 V DC, with a residual ripple of 0 - 15% from UB. The open - circuit current is maintained at 0 - 15 mA. It features one digital switching output with an NPN transistor, and the switching principle is light/dark reversible. A teach input with a static 2 - point process allows for easy calibration. With a switching frequency of 10,000 Hz, it can quickly respond to changes in the detected objects. Additionally, it has short - circuit protection, ensuring stable operation even in potentially risky electrical conditions.
Durable and Versatile Design
Constructed with a plastic housing, the KRTW 3B/2.1121 - S8 is both lightweight and durable. Measuring compactly, it can be easily integrated into various industrial setups. The IP 67 protection rating safeguards it against dust and water, suitable for use in harsh environments. It has a c UL us approval, adhering to safety standards. The M8 connector simplifies the connection process. Whether in a manufacturing plant with high humidity or a dusty warehouse, this sensor's robust design and reliable performance make it a suitable choice for a wide range of industrial applications, from logistics to automotive production lines.
