The Banner DQ12AB6R is a compact and rugged photoelectric sensor engineered for opposed-mode sensing, offering superior accuracy and reliability in industrial automation. Designed as part of the Q12 family, this model is built to deliver precise detection in space-constrained installations while withstanding demanding environmental conditions.

In its opposed-mode sensing configuration, the DQ12AB6R works with a paired emitter and receiver. Detection occurs when an object breaks the light beam between the two units, ensuring extremely accurate and consistent performance. This method provides greater sensing range and immunity to background interference compared to diffuse or retroreflective sensors. The opposed setup is especially useful in high-speed manufacturing environments or applications where small, irregular, or low-reflectivity objects must be reliably detected.

The sensor uses a visible red LED beam, making it easy for operators and technicians to align during setup. The bright, focused spot allows quick confirmation of the sensing path, reducing installation time and minimising errors. During operation, the visible beam also provides clear feedback, enabling simple maintenance checks and improving overall system efficiency.

Supplied with a 2 m pre-wired cable, the DQ12AB6R offers flexibility for integration into control cabinets, junction boxes, or PLCs. The fixed cable design ensures secure and stable connections, minimising potential points of failure. Its length supports clean and efficient routing in both compact and mid-sized installations, helping reduce clutter and streamline wiring.

Engineered for durability, the sensor carries an IP67 protection rating, providing complete sealing against dust ingress and reliable resistance to water exposure, including temporary immersion. This rugged environmental protection ensures dependable operation even in harsh industrial conditions, such as dusty packaging facilities, wet washdown areas, or vibration-prone assembly environments.

The Q12 rectangular housing offers a compact footprint, making the DQ12AB6R ideal for machinery with limited space. Despite its slim size, it is built to Banner’s high-quality standards, ensuring long service life and consistent performance in continuous-use applications.

Common applications include part detection on conveyors, small component verification in assembly lines, counting objects in high-speed packaging systems, and presence detection in material handling. Because of its opposed-mode design, the DQ12AB6R provides excellent reliability in scenarios where reflective surfaces, variable object colours, or environmental interference would limit the performance of other sensing modes.

In summary, the Banner DQ12AB6R Opposed-Mode Photoelectric Sensor combines visible red LED alignment, IP67-rated durability, a 2 m pre-wired cable, and compact Q12 housing into a robust sensing solution. Designed for precision, ease of integration, and resilience, it is an excellent choice for automation engineers seeking dependable object detection in today’s challenging industrial environments.
