The Banner K50APTGBYF2Q is a durable and versatile capacitive touch button with discrete output, engineered to provide intuitive operator input and clear status indication in demanding industrial environments. Part of Banner’s proven K50 series, this device combines ergonomic touch activation with vibrant multicolour LED illumination, simplifying machine control and operator guidance while enhancing safety and efficiency.

At the core of the K50APTGBYF2Q is its capacitive touch sensing technology, which eliminates the need for mechanical components. Unlike traditional push buttons that rely on moving parts, capacitive sensors register a user’s touch through the smooth dome surface. This ensures long service life, minimal wear, and reliable actuation even when operators are wearing gloves. The flat, crevice-free dome also improves hygiene and is easy to clean, making it ideal for industries with strict sanitation requirements such as food and beverage or pharmaceuticals.

The device operates on a 12–30 V DC supply, offering compatibility with standard automation and control systems. Its discrete output makes it straightforward to integrate into PLCs, machine inputs, or workstation controls. The stable electronic design provides consistent actuation signals, even in electrically noisy environments, ensuring accurate and reliable performance in high-speed or precision-critical operations.

One of the key advantages of the K50APTGBYF2Q is its multicolour LED indication. With the ability to display green, blue, and yellow light, this single device can communicate multiple system states or workflow steps. For example, green may signal “ready,” blue can indicate “in progress,” and yellow can represent “warning” or “attention needed.” This versatility reduces the need for multiple indicator lights, streamlines panel design, and provides operators with immediate, intuitive feedback. The 50 mm dome housing ensures wide-angle visibility and can be easily recognised on busy factory floors or from a distance.

Built for industrial durability, the K50APTGBYF2Q is rated IP67 and IP69K, ensuring complete protection against dust and water ingress, including high-pressure, high-temperature washdowns. This rugged design makes it well suited for use in harsh production environments, including packaging, logistics, material handling, and cleanroom applications where equipment reliability is critical.

The compact dome housing simplifies installation and provides a stable mounting solution. It can be integrated into operator panels, workstations, or directly onto machinery, ensuring flexibility in deployment while maintaining robust performance.

In practical use, the K50APTGBYF2Q is ideal for machine start/stop control, pick-to-light systems, operator guidance, workstation feedback, and process verification. By combining intuitive actuation with bright, versatile indication, it enhances operator efficiency, reduces error rates, and supports lean manufacturing practices.

In summary, the Banner K50APTGBYF2Q is a high-performance touch button indicator that brings together capacitive actuation, discrete output, and multicolour LED feedback in a rugged, washdown-ready design. With its 12–30 V DC supply range, IP67/IP69K protection, and versatile indication capabilities, it delivers long-lasting performance in the most demanding automation environments.
