The Banner K50LGRB2PQ is a durable, multi-colour indicator engineered to provide highly visible and reliable signalling in industrial environments. As part of Banner’s K50 series, this model combines rugged construction, versatile LED outputs, and discrete input control, making it an excellent solution for machine status indication, operator guidance, and lean manufacturing systems.

Equipped with three-colour LED illumination (green, red, and blue), the K50LGRB2PQ offers clear communication of machine or process conditions in a single device. Green can indicate “ready” or “normal operation,” red can highlight errors or stop conditions, and blue can serve as a user-prompt or special instruction. This multi-colour functionality helps streamline workflows by eliminating the need for multiple indicators while ensuring operators receive clear and immediate feedback. The LEDs are designed to provide uniform, bright illumination, making them easy to see in both bright factory lighting and dimmer environments.

The device is built to withstand demanding industrial conditions, carrying IP67 and IP69K ratings. These certifications guarantee full protection against dust ingress and resilience to water exposure, including high-pressure, high-temperature washdowns. This makes the K50LGRB2PQ ideal for hygienic applications in food and beverage processing, pharmaceuticals, and packaging, as well as in general manufacturing environments that require rugged and reliable components. Its robust housing also provides resistance to vibration, impacts, and mechanical wear, ensuring long service life even under heavy-duty use.

The indicator supports discrete input control, allowing individual colours to be triggered directly by control systems such as PLCs, switches, or relays. This flexibility ensures easy integration into a variety of workflows, enabling users to tailor the device’s colours to specific machine states, operator prompts, or process steps. Discrete control also ensures reliable communication of status signals without the complexity of networked systems, making it both simple and dependable.

Operating on a wide supply voltage range of 18–30 V DC, the K50LGRB2PQ is compatible with common industrial power infrastructures. Its straightforward wiring and Banner’s standardised K50 housing design make installation quick and efficient. The energy-efficient LED design also reduces maintenance demands, providing consistent operation over an extended service life.

Applications for the K50LGRB2PQ include machine status monitoring, assembly verification, operator guidance in pick-to-light systems, quality inspection, and workflow signalling in lean manufacturing environments. For example, it can be used to direct operators during assembly tasks, indicate machine states on production lines, or provide traffic-style signalling in warehouse processes. Its versatility and rugged construction make it suitable for nearly any industrial environment requiring dependable visual communication.

In summary, the Banner K50LGRB2PQ combines three-colour LED indication, IP67/IP69K environmental protection, discrete input control, and wide DC voltage compatibility into a durable, high-performance indicator. Engineered for resilience, clarity, and flexibility, it is a trusted solution for industries seeking to improve visibility, operator awareness, and efficiency in demanding automation applications.
