The Banner K50APT2GREQ is a rugged, high-visibility LED touch button designed to provide both intuitive operator input and reliable visual feedback in challenging industrial environments. Part of the well-established K50 series, this model combines touch activation technology, long-life LED illumination, and robust environmental protection, making it an excellent solution for machine control, operator guidance, and process monitoring applications.

Operating on a 12–30 V DC supply voltage, the K50APT2GREQ ensures compatibility with a wide range of industrial control architectures. Its broad input range allows engineers and technicians to easily integrate the device into both new and existing automation systems, ensuring stable and reliable operation even under variable power conditions.

The button features a capacitive touch interface that enables activation with a simple touch. Unlike traditional mechanical push buttons, capacitive technology eliminates moving parts, reducing wear and tear while extending service life. The design also allows activation through most work gloves, ensuring convenience and reliability in environments where protective gear is required.

Equipped with multicolour LED illumination (Green, Red, Amber), the K50APT2GREQ provides immediate visual feedback, clearly communicating machine or process states to operators. The dome-style lens ensures even light distribution with high visibility from multiple viewing angles, making it easy for workers to interpret signals at a glance—even in brightly lit environments.

Built for harsh conditions, the K50APT2GREQ carries IP67 and IP69K protection ratings, ensuring complete resistance to dust ingress and the ability to withstand high-pressure, high-temperature washdowns. In addition, the rugged housing construction meets industry requirements for environments where frequent cleaning, exposure to oils, or vibrations are common. These protections make the unit ideal for industries such as food and beverage, pharmaceuticals, packaging, material handling, and automotive manufacturing.

The device is designed with a discrete output, simplifying integration into PLCs, machine controllers, and safety systems. Its straightforward on/off signalling makes it versatile for a range of applications, from start/stop functions to operator call systems, quality control checkpoints, or workstation guidance.

In real-world applications, the K50APT2GREQ is commonly used in pick-to-light systems, assembly lines, workstation feedback, and operator call systems. For example, in a packaging line, it can be used to indicate process completion and allow an operator to acknowledge readiness for the next step. In assembly environments, it provides quick feedback for quality checks, reducing errors and supporting lean manufacturing practices.

In summary, the Banner K50APT2GREQ combines capacitive touch activation, bright multicolour LED indication, robust IP67/IP69K protection, and discrete output capability into a reliable and efficient operator interface device. Compact yet powerful, it enhances communication, improves workflow efficiency, and ensures reliable operation even in the most demanding industrial settings.
