The Banner Q3XTBLD-Q8 delivers 300 mm max sensing distance with a visible red Class 2 laser beam, ensuring accurate contrast detection even in high-speed environments. It operates on a 10β30 V DC power supply and provides bipolar NPN & PNP outputs for flexible integration. This discrete I/O laser contrast sensor features a 0.25 ms response time, 60 Β΅s repeatability, and 655 nm beam wavelength, making it highly suitable for fast-paced automation lines. The sensor includes a Teach button for easy configuration, while its M12 connector and 5-pin interface simplify wiring in compact installations. With a rugged nickel-plated rectangular housing and M18 mounting, it withstands harsh operating conditions ranging from -10Β°C to +50Β°C, and supports up to 95% relative humidity. Certifications like IP67, IP68, IP69K and NEMA 4X ensure reliable sealing against dust, water, and washdowns, essential for hygiene-critical environments.
What makes the Banner Laser Contrast Sensor Q3XTBLD-Q8 particularly powerful is its diffuse/background suppression sensing mode, which allows it to accurately detect light/dark or mark/no-mark transitions on fast-moving materials. It's ideal for industries where label presence, registration marks, or part differentiation is keyβsuch as packaging lines, print-mark detection, product sorting, labeling machines, and food & beverage bottling systems. Its compact form factor and precise laser spot make it well-suited for limited-space applications without sacrificing detection accuracy.
With quick teach-in setup, durable design, and fast performance, the Banner Q3XTBLD-Q8 stands out among contrast sensors in the market.
