Introduction
In the realm of industrial human-machine interfaces (HMIs), display performance under harsh conditions is non-negotiable. Engineers designing for automation, medical devices, or outdoor instrumentation require displays that combine reliability, clarity, and durability. The 3.5-inch TFT LCD module (SF-TC350M-9268A1-N) from Saef Technology Limited is engineered to address these exacting demands.
Key Features & Design Advantages
Wide Operating Temperature Range
With an operational range of -20°C to 70°C and storage tolerance from -30°C to 80°C, this display is built for environments where thermal stability is critical.
High Brightness & Optical Performance
Boasting a typical luminance of 400 cd/m² and a contrast ratio of 250:1, the module ensures readability even under direct sunlight or high-ambient light conditions.
Robust Interface & Driver Compatibility
Equipped with an RGB interface and the HX8238D driver IC, it supports both SPI and parallel communication, offering flexibility for embedded systems.
Integrated Touch Panel Option
While the base model includes a 4-wire resistive touch panel with 82% transparency and 1,000,000-touch durability, Saef Technology Limited also offers customized capacitive or resistive touch solutions to fit specific HMI architectures.
Why This Matters for German & US Engineers
In markets where compliance with ISO9001/14001 and MIL-STD is often a prerequisite, this module’s adherence to rigorous quality and environmental standards makes it a dependable choice. Its 3.5-inch form factor fits compact control panels without sacrificing resolution or usability.
Conclusion
For engineers seeking a display that balances performance with resilience, the SF-TC350M-9268A1-N offers a proven solution. Its optical characteristics, environmental robustness, and optional touch integration make it ideal for next-generation industrial HMIs.
