The Banner K50APFF100GRYC3Q is an advanced touchless optical button designed to enhance machine interaction in environments where hygiene, durability, and ease of use are critical. As part of Banner’s K50 series, this model eliminates the need for physical contact by using optical detection technology, reducing wear and tear while promoting hands-free operation. Equipped with a multicolour LED indicator (green, red, yellow), it provides operators with immediate visual feedback on machine or process status, streamlining workflow and improving overall efficiency.

Operating on a 12–30 V DC supply, the K50APFF100GRYC3Q integrates easily into standard automation and control systems. Its wide voltage tolerance ensures stable operation, making it a dependable solution for continuous-duty industrial applications. The touchless design reduces the risk of contamination in sensitive environments such as food and beverage processing, life sciences, packaging, and pharmaceuticals, while also extending the device’s lifespan compared to mechanical switches.

The K50APFF100GRYC3Q is engineered with IP67 and IP69K ingress protection ratings, ensuring complete resistance to dust ingress and high-pressure washdowns. Additionally, it is certified to UL Type 4X and 13, guaranteeing resistance to corrosion, oil, non-corrosive liquids, and industrial contaminants. This makes it suitable for the most demanding environments, including hygienic washdown zones and areas subject to vibration, moisture, or exposure to cleaning agents. Its robust housing ensures consistent performance and reduces the risk of downtime due to environmental factors.

With its touchless operation, the K50APFF100GRYC3Q supports improved safety and hygiene by eliminating physical contact points where dirt, bacteria, or wear could accumulate. Operators activate the device by simply placing their hand within the detection field, and the sensor responds with visual LED indication. The integrated LED ring, which supports multiple colours, ensures clear, visible feedback for machine states such as ready, active, or fault conditions. This functionality improves operator awareness and helps reduce errors in fast-paced work environments.

The display-free design ensures straightforward operation while minimising complexity. By focusing on durability and visual feedback rather than user-programmable displays, the K50APFF100GRYC3Q offers a simplified yet highly effective solution for industrial control. The lack of mechanical moving parts further enhances its longevity, lowering maintenance costs and ensuring consistent performance over extended periods of operation.

Applications for the K50APFF100GRYC3Q are broad and include machine start/stop controls, operator input in hygienic environments, visual status indication, packaging line controls, and workflow management. Its hygienic, touch-free design is particularly valuable in industries with strict cleanliness standards, while its robust construction makes it equally suitable for heavy-duty industrial use.

In summary, the Banner K50APFF100GRYC3Q delivers a hands-free, hygienic operator interface with multicolour LED indication, rugged IP67/IP69K protection, 12–30 V DC operation, and UL Type 4X/13 durability. Combining the simplicity of a push button with the safety and reliability of touchless sensing, it provides engineers and system designers with a modern, long-lasting solution for machine interaction in demanding industrial environments.
