PART NO.: CK-FU11627 CK-FU11627 IP67 & IK09 4-Key Stainless Steel Industrial Function Keypad The CK-FU11627 is a compact, ultra-rugged 4-key industrial function keypad engineered for public self-service terminals and harsh industrial control systems. Featuring top-tier IP67 waterproof/dustproof and IK09 vandal-proof ratings, this panel-mount keypad adopts premium brushed 304 stainless steel construction, delivering exceptional resistance against dirt, dust, water, ice, oil and various harsh contaminants. With a miniature lightweight design and fully sealed structure, it serves as a perfect customized auxiliary input solution for space-limited industrial and public equipment scenarios. Built with a 1.5mm thick solid stainless steel front panel and rear mounting screw design, the keypad ensures firm, stable embedded installation and excellent anti-collision, anti-vandal performance for long-term high-frequency public use. The integrated one-piece internal rubber structure achieves full sealing, completely blocking water, dust and fine particles from penetrating the internal components to meet strict IP67 industrial protection standards. Adopting professional laser etching and special ink-filling technology for key characters, it effectively prevents letter wear and fading, maintaining permanent clear key identification after millions of pressing cycles. Equipped with high-quality metal dome key switches, the keypad features an ultra-slim 0.5mm key travel and a stable 2.0N±0.2N actuation force, providing crisp, consistent tactile feedback and precise operation experience. The ultra-flat seamless surface avoids dust and dirt accumulation, enabling effortless daily cleaning and maintenance, ideal for sanitary and high-cleanliness working environments. To meet diverse personalized usage demands, the product supports rich customization options, including multi-language layouts, special functional symbols, raised letters and raised braille dots, fully adapting to global and special industrial application requirements. Supporting multiple universal interfaces including Matrix, USB, PS/2 and RS232 with plug-and-play functionality, the keypad features ultra-wide device compatibility and fast deployment without complex debugging. It is engineered with outstanding extreme environmental adaptability, operating stably in a wide temperature range of -20°C to +60°C and supporting safe long-term storage at -30°C to +70°C. It has passed rigorous IEC 60512-6 industrial reliability tests, including 96-hour salt mist resistance, 21-day damp heat endurance at 40°C and 10-day dry heat resistance at 85°C, with 100% full humidity resistance for stable operation in humid, corrosive and oily harsh environments. This mini industrial keypad boasts superior long-term operational reliability and cost performance. Its metal dome switches support up to 5 million pressing operations, with an average overall service life of more than 6 years. It achieves excellent industrial reliability indicators: MTBF over 50,000 hours and MTTR less than 30 minutes, greatly reducing equipment failure rates and daily maintenance costs. Featuring an ultra-compact size of 116.0mm × 27.0mm and an ultra-light gross weight of only 0.2KG, it perfectly fits narrow installation spaces and lightweight equipment assembly. With an ultra-low rated current of 20mA and compliance with EN55022(B) EMC emission standards, it ensures low power consumption and stable electromagnetic compatibility for long-term continuous opera
