The Banner Q20NLV: 77767 is engineered for long-range detection applications, offering a maximum sensing distance of 6000 mm. It uses a Visible Red LED light source at 645 nm wavelength, allowing for easy beam alignment and visibility during setup. Designed with a Non-Polarized retro-reflective sensing mode, it detects reflective objects or returns from a standard reflector without needing polarization filters, making it versatile for various material types. The sensor operates on a 10–30 V DC power supply, outputs an NPN discrete signal, and is equipped with a 2-meter cable for quick installation. With a fast response time of 0.8 ms and potentiometer adjustment, it ensures stable operation even in rapidly changing conditions.
Its durable thermoplastic housing is shaped in a compact rectangular form, rated for IP67 and NEMA 4X environmental protection. These ratings ensure the sensor remains functional in the presence of water spray, dust, and industrial cleaning agents. It includes LED indicators for real-time status updates and features a clear acrylic lens that enhances optical performance. With an operating temperature range of -20°C to +60°C and a repeatability of 155 µs, this model performs reliably across a wide variety of applications and environments. The Q20NLV is known for its simple setup, high stability, and robust build, making it a dependable choice in harsh industrial settings.
Applications of Q20NLV: 77767 - Banner Non-Polarized Retro-reflective Sensor
The Q20NLV is ideal for applications in automated packaging, conveyor systems, bottling plants, and warehouse automation where long-range, accurate object detection is required. Its non-polarized design allows it to sense transparent or reflective surfaces more easily compared to polarized sensors, making it suitable for detecting plastic containers, shrink-wrapped items, or glossy surfaces. Engineers benefit from its broad sensing range and easy alignment process, reducing setup time and maintenance effort. In high-throughput environments, its fast response and stable signal output improve production efficiency and reduce false positives. Maintenance engineers also value its rugged construction, which ensures reliable performance over time even in vibration-prone or moisture-heavy conditions.
