QS18VP6LPQ: 61631 - Banner Polarized Photoelectric Sensor

The QS18VP6LPQ from Banner is a trusted Polarized Photoelectric Sensor built for environments where accurate detection and compact form factor are essential. With a maximum sensing distance of 3500 mm and a visible red laser beam operating at 630 nm, it ensures consistent detection of reflective targets while filtering out background interference. It is housed in a robust rectangular ABS body with an M18 mount, offering both durability and ease of integration into existing setups. Engineered for reliability, the sensor is IP67-rated and NEMA 4X compliant, protecting it against water, dust, and harsh industrial conditions. Its discrete PNP output and 4-pin M8 quick-disconnect connection simplify wiring and maintenance. The 10–30 V DC power supply range supports flexibility in various control systems. Key performance features include a rapid response time of 0.6 ms, repeatability of 150 µs, and a 100 ms power-up delay, allowing for fast and stable operation. The sensor is also equipped with a potentiometer for manual sensitivity adjustments, along with an acrylic lens and built-in LED indicators for clear status visibility, even in low-light conditions.

Applications of Banner QS18VP6LPQ

The QS18VP6LPQ Banner Sensor is ideal for industrial processes that demand stable detection of shiny or reflective surfaces. Common applications include packaging lines where it detects bottles, cans, or foil-wrapped items with precision, and automated conveyors where it identifies product presence despite metallic or polished backgrounds. Its polarization filter minimizes false triggers from background reflections, which is essential in tight spaces with complex lighting conditions. Additionally, this model is suited for robotic arms and material handling systems that require compact sensors with long-range capabilities. Engineers often deploy it in machinery safety interlocks, filling lines, and object counting systems where speed, accuracy, and signal stability are critical. Educational institutions and training labs also use it to introduce students to advanced sensing techniques used in modern industrial control. With its smart design and reliable performance, the QS18VP6LPQ remains a dependable solution for automation engineers seeking a balance of compactness and capability.
