The Banner QS18UNAE is a versatile and rugged ultrasonic sensor designed to deliver reliable detection in challenging automation environments. As part of the proven QS18 series, it combines Banner’s durable housing with advanced ultrasonic technology, offering a dependable solution for applications where photoelectric sensors may be limited by target transparency, reflectivity, or surface irregularities.

At the heart of the QS18UNAE is its ultrasonic sensing beam, which measures distance by transmitting high-frequency sound waves and detecting their return. This allows the sensor to reliably detect targets regardless of color, transparency, or surface finish. It excels in applications where optical sensors may fail, such as with clear plastic bottles, reflective metal surfaces, or uneven objects. This versatility makes it highly valuable in packaging, material handling, food and beverage, and automotive industries.

The sensor is equipped with a 2-meter cable, offering flexibility for installation in standard machine layouts. The cable length is long enough to accommodate typical wiring routes without adding unnecessary slack, ensuring efficient integration into control panels and junction boxes. Combined with its compact QS18 housing, the QS18UNAE is easy to mount in both new systems and retrofit projects.

Built for tough environments, the QS18UNAE carries IP68 and NEMA 4X ratings, making it fully dust-tight, resistant to water immersion, and capable of withstanding high-pressure washdowns. Its rugged thermoplastic housing protects sensitive ultrasonic components against vibration, shock, and exposure to harsh environmental conditions. This durability ensures long service life even in demanding industries such as food processing, outdoor automation, or heavy equipment manufacturing.

The sensor operates on a 12–30 V dc power supply, providing broad compatibility with industrial control systems. This wide voltage range makes the QS18UNAE suitable for integration into diverse applications while ensuring energy-efficient performance and safe operation.

Typical uses of the QS18UNAE include liquid level monitoring, presence/absence detection, object counting, distance measurement, and packaging verification. For example, it can monitor fill levels in containers, detect the presence of products on a conveyor regardless of material type, or confirm the positioning of parts in assembly operations. Its ultrasonic technology ensures stable results in scenarios where ambient light, dust, or target reflectivity might cause issues for optical alternatives.

In summary, the Banner QS18UNAE ultrasonic sensor offers reliable detection in applications that challenge traditional sensing methods. With its ultrasonic beam technology, IP68/NEMA 4X environmental protection, 2-meter cable length, and wide 12–30 V dc operating range, it delivers dependable performance in harsh conditions. For engineers and integrators seeking a rugged, accurate, and versatile detection solution, the QS18UNAE is an excellent choice.
