The Banner QS18VN6AF350 is a rugged and versatile photoelectric sensor from Banner’s popular QS18 series, designed to provide reliable object detection in a wide range of industrial automation applications. With a compact housing, visible red LED sensing beam, and robust environmental protection, this sensor is well-suited for applications that demand precision, durability, and ease of integration.

At the heart of the QS18VN6AF350 is its visible red LED sensing beam, which projects a bright, easily identifiable spot. This makes installation and alignment straightforward, as operators can quickly verify the sensing path during setup. The visible beam also helps with troubleshooting and performance checks during operation, providing real-time feedback and reducing downtime. Once aligned, the sensor delivers repeatable and accurate detection, even in high-speed processes or applications with variable product surfaces.

Operating on a 10–30 V DC supply voltage, the QS18VN6AF350 offers wide compatibility with standard industrial power systems. This flexible operating range ensures stable performance and easy integration into both new and existing automation setups. Its design allows seamless connection with PLCs, machine controllers, or distributed I/O modules, making it a reliable choice for diverse control architectures.

The sensor is engineered for harsh industrial environments, carrying an IP67 rating and NEMA 4X certification. These ratings guarantee dust-tight construction, resistance to water spray, and suitability for washdown applications. The NEMA 4X rating also provides additional corrosion protection, making the QS18VN6AF350 a dependable solution in industries such as food and beverage, packaging, automotive, logistics, and material handling. Its rugged build reduces the risk of premature failure, ensuring long service life and lower maintenance costs.

With its 2 m pre-wired cable, the sensor provides secure and flexible wiring options. The fixed-cable design minimizes connection points, reducing potential failure risks compared to connector-based models. This ensures dependable long-term operation and easy routing into panels, junction boxes, or control systems.

The compact QS18 housing makes the QS18VN6AF350 easy to install in tight or space-constrained areas. Its slim rectangular profile supports mounting flexibility while maintaining Banner’s standard for industrial-grade reliability.

Practical applications include package detection on conveyors, part presence verification in assembly lines, object counting, and position sensing in material handling systems. Its visible red LED and durable housing make it particularly valuable in applications requiring frequent operator interaction, quick sensor verification, and rugged performance under demanding conditions.

In summary, the Banner QS18VN6AF350 Photoelectric Sensor combines visible red LED accuracy, wide 10–30 V DC compatibility, rugged IP67/NEMA 4X protection, and a reliable 2 m cable in one compact package. Designed for durability, ease of alignment, and reliable detection, it is an excellent choice for engineers and system designers looking to improve efficiency and consistency in industrial automation.
