The Banner Q20NLP: 77763 is engineered for performance in demanding applications, offering a maximum sensing distance of 4000 mm through its polarized retro-reflective mode. It emits a visible red LED beam at 645 nm wavelength, enabling accurate alignment and minimizing false detection from reflective surfaces. Operating on a standard 10–30 V DC power supply, it provides NPN discrete output and connects via a 2-meter cable for straightforward installation into control systems and PLCs. The sensor delivers a fast response time of 0.8 ms and features a potentiometer adjustment for tuning detection sensitivity based on target reflectivity.
This Photoelectric Sensor is enclosed in a durable thermoplastic rectangular housing, rated IP67 and NEMA 4X for protection against water, dust, and corrosion. It is built to operate reliably across temperatures ranging from -20°C to +60°C, with LED indicators for power and output status monitoring. A PMMA acrylic lens ensures consistent optical clarity, while a repeatability of 155 µs guarantees high accuracy in repeated sensing cycles. Its robust design and adaptable integration make the Q20NLP ideal for modern industrial environments where stable, long-range detection is required without complex configurations.
Applications of Q20NLP: 77763 - Banner
The Q20NLP is trusted across a variety of sectors including material handling, packaging, conveyor systems, and automated storage units. It is particularly effective in scenarios where objects with varying surface finishes—such as glossy, clear, or colored materials—must be detected from long distances without interfering backgrounds. The polarized design helps reject unwanted reflections from shiny metal or plastic surfaces, making it a preferred choice for engineers in high-speed production lines. Maintenance technicians value its easy alignment, fast setup via potentiometer, and consistent detection stability over years of operation. Whether monitoring product flow, gate positions, or presence verification, this sensor plays a crucial role in reducing downtime and ensuring process continuity across automated operations.
