The Banner QS18UPAQ5 Ultrasonic Sensor is a versatile and rugged sensing solution engineered to deliver consistent performance in a wide range of industrial applications. Designed with Banner’s trusted QS18 housing style, it combines ultrasonic detection with durable construction and flexible integration options, making it ideal for environments where traditional photoelectric sensors may struggle.

At its core, the QS18UPAQ5 utilises an ultrasonic sensing beam, which measures distance and detects objects based on sound waves rather than light. This allows it to sense objects regardless of colour, reflectivity, or transparency—something that optical sensors often cannot achieve. Whether detecting clear plastic bottles, shiny metal surfaces, or irregularly shaped parts, the QS18UPAQ5 provides reliable and accurate detection. This makes it especially valuable in industries such as packaging, food and beverage, and material handling.

The unit comes with a 0.15 m pigtail cable, which is designed for use with quick-disconnect connectors. This compact wiring option streamlines installation in tight spaces and allows for fast replacement or reconfiguration when necessary. The pigtail style also minimises cable clutter and enhances system flexibility, ensuring that the sensor can be deployed easily in both new and existing setups.

Engineered for demanding environments, the QS18UPAQ5 carries an IP67 and NEMA 4X rating, making it resistant to dust, moisture, and washdown conditions. The IP67 protection ensures dust-tight performance and protection against temporary water immersion, while the NEMA 4X rating provides additional resistance to corrosion and water exposure. This robust environmental protection allows the sensor to be confidently deployed in applications where exposure to liquids or contaminants is common, such as food processing lines, outdoor installations, or washdown areas.

Operating on a supply voltage range of 12–30 V DC, the QS18UPAQ5 integrates seamlessly into standard industrial control systems. Its broad voltage tolerance ensures stable operation and compatibility across a wide variety of setups, eliminating the need for specialised power conditioning equipment.

Practical applications of the QS18UPAQ5 include level detection in tanks and hoppers, presence sensing on conveyor systems, clear object detection in packaging lines, and part positioning in automated equipment. The ultrasonic beam ensures that the sensor delivers reliable results in situations where optical sensors would fail due to colour, gloss, or transparency of the target.

In summary, the Banner QS18UPAQ5 Ultrasonic Sensor offers a powerful combination of ultrasonic detection capability, compact quick-disconnect wiring, rugged IP67/NEMA 4X protection, and wide DC voltage compatibility. Designed for industries that demand accuracy and resilience in challenging conditions, it is a dependable choice for automation engineers seeking versatile sensing solutions that work where light-based sensors cannot.
