KT series mark detection photoelectric switches are issued through its own light source scanning the surface of the material was seized. The difference in color due to surface leaving different amount of light reflected back, so as to achieve the color identification mark.
Coaxial optical design, high reflection coefficient of paper (such as aluminum foil, etc.) and adaptable. With blue, green, red and other sources available, bring convenience for distinguishing different colors. Spot small, high resolution 0.1-1ms a high response speed. Able to adapt to a variety of packaging machines, bag making machines and printing machinery control needs. Excellent in circuit design, a variety of anti-electromagnetic, stray light interference, excellent performance, stable operation, and correct action. With sensitivity adjustment knob, do not require the use of tools to adjust.
