The Keyence VT3-Q5S is a robust and versatile Human-Machine Interface (HMI) designed to deliver excellent performance in industrial automation and control applications. With its 5-inch QVGA STN colour touch panel, it provides operators with a highly reliable and intuitive interface for managing equipment, monitoring processes, and visualizing production data in real time.

One of the most notable features of the VT3-Q5S is its high-quality colour display. The unit employs an STN colour LCD with 32,768 colours and a resolution of 320 × 240 pixels, ensuring clear, sharp, and detailed visual output. This makes it easy for operators to interpret graphical data, monitor system conditions, and respond quickly to alarms or process variations. The display also provides an active viewing area of 115.2 × 86.4 mm, giving ample space for displaying critical process information.

In terms of durability and environmental resistance, the VT3-Q5S is built to endure demanding industrial settings. Its panel-built structure is designed to meet IP65f standards, offering dust-proof and waterjet-proof protection on the front panel. This makes it ideal for environments with dust exposure or occasional liquid splashes. Furthermore, it has been tested for vibration resistance, withstands a wide temperature range from 0 to +50°C, and maintains stable operation even under challenging factory conditions.

The touch interface is designed for both performance and reliability. Using a matrix resistive film system, the VT3-Q5S provides highly accurate input with an operating force of 0.98N or less. Its durability is exceptional, supporting over 1,000,000 operations, making it suitable for applications where the panel will be in constant use. This ensures both long service life and dependable responsiveness.

The unit is also equipped with robust memory and data management features. With 4 MB of internal memory, the VT3-Q5S can store up to 1024 pages and thousands of registered screens, including global windows and report screens. Its flash ROM supports up to 100,000 erase cycles, ensuring reliable long-term data management. Additionally, a built-in lithium battery provides SRAM backup for recording data and supports a calendar timer with ±40 seconds/month accuracy, guaranteeing data security and precise time tracking even in the event of power loss.

The backlight system utilizes a cold-cathode tube with an impressive lifespan of approximately 75,000 hours, ensuring long-lasting performance. Combined with the display’s service life of around 50,000 hours, the VT3-Q5S reduces maintenance demands and delivers consistent, uninterrupted operation.

In summary, the Keyence VT3-Q5S is a powerful, durable, and user-friendly HMI that combines advanced display quality, strong environmental resistance, reliable input performance, and comprehensive memory management. It is well-suited for manufacturing lines, automated machinery, and any industrial environment where precise, long-term operator interaction with machines is critical.
