The Banner K50APLPGRCQ is a robust touchless optical button designed to provide safe, hygienic, and highly visible operator input in industrial and commercial environments. Using advanced optical sensing technology, this device eliminates the need for physical contact, enabling users to activate functions with a simple hand gesture. Its rugged build, high visibility, and sanitary design make it ideal for industries that require reliability and cleanliness in equal measure.

Operating on a 12–30 V DC supply voltage, the K50APLPGRCQ integrates easily into standard control systems, offering reliable performance and broad application flexibility. The wide voltage tolerance ensures compatibility with a variety of installations, from new systems to retrofitted equipment, without the need for specialised power conditioning.

The standout feature of this model is its touchless actuation capability, which allows operators to trigger the button by waving a hand or presenting it within the sensing field. This not only reduces wear and tear but also extends the life of the device by eliminating moving parts typically subject to mechanical failure. More importantly, the contactless operation improves hygiene by reducing the risk of cross-contamination, a critical advantage in food and beverage, pharmaceutical, healthcare, and cleanroom industries.

To complement its touchless functionality, the K50APLPGRCQ is equipped with bright multi-colour LED indicators that provide immediate visual confirmation when activated. The illumination is clearly visible across a wide viewing angle, even in bright industrial lighting conditions. By providing operators with unambiguous status feedback, the device reduces errors and improves process efficiency.

Built for reliability in harsh environments, the K50APLPGRCQ is sealed to IP67 and IP69K standards, protecting it against dust, water immersion, and high-pressure, high-temperature washdowns. Its compliance with UL Type 4X and 13 ratings adds corrosion resistance and protection against oils and non-corrosive coolants, making it well-suited for facilities where rigorous cleaning or exposure to industrial fluids is routine. This combination of durability and hygiene protection ensures long-term, consistent performance even in demanding conditions.

The button’s smooth, display-free housing is easy to clean and resistant to residue build-up, supporting its use in sanitary or high-traffic environments. By eliminating mechanical actuation, the device not only improves hygiene but also significantly reduces maintenance requirements, minimising downtime and overall cost of ownership.

Practical applications for the K50APLPGRCQ include machine start/stop functions, call-for-service buttons, workstation feedback, and operator acknowledgement tasks. In packaging or assembly lines, it can act as a durable input device for operators, while in food production or healthcare environments it provides a safe, hands-free interface that aligns with strict hygiene protocols.

In conclusion, the Banner K50APLPGRCQ combines touchless optical technology, rugged IP67/IP69K and UL-rated housing, wide DC power compatibility, and high-visibility LED feedback in a compact, durable design. It is the ideal solution for industries seeking a long-lasting, contamination-resistant alternative to mechanical push buttons that enhances both hygiene and reliability.
