The growing demands placed on modern electronics increase the need for components that combine reliability, flexible integration, and contemporary design. The answer to these needs is the UCB045-RGB-CMFDV1 – a capacitive touch button developed by the Unisystem team, designed to operate in extreme conditions. This article presents the key features of this product, the situations where it succeeds where other solutions fail, and the potential areas of its application.
Advanced Touch Technology – Precision and Reliability
The UCB045-RGB-CMFDV1 is built around an integrated circuit, offering exceptionally high touch detection sensitivity and stable operation. Advanced algorithms ensure reliable touch recognition even in conditions that could compromise the performance of other similar solutions.
The high reliability of the device means it can operate long-term without failures, maintaining consistent and stable parameters. Designers can therefore rely on the UCB045-RGB-CMFDV1 as a component that will not be a source of malfunctions or system downtime.
Key Features
The button’s reliable performance in industrial environments is ensured by a set of design solutions that provide resistance to harsh conditions and eliminate the risk of unwanted events.
- Accurate touch detection through protective glass – the sensor responds precisely even when an additional protective layer is used. By default, it is configured for 1.1 mm glass, but after proper calibration it can also work with glass up to 4 mm thick. If needed, we provide support in adjusting parameters to the requirements of a specific application.
- Glove operation – sensitivity is maintained, allowing comfortable use of the button even when wearing gloves. This is particularly important in industrial, medical, and laboratory environments where hand protection is standard practice.
- Stable operation in the presence of liquids – the button functions correctly even when scattered water droplets are present on the surface. Proper calibration eliminates the risk of so-called ghost touches, and in the event of flooding with larger amounts of liquid, the system automatically ignores interference, preventing unintended activations.
In addition, the module is adapted to operate within a wide temperature range from -20°C to +70°C, ensuring full functionality both in demanding industrial conditions and in outdoor environments.
Light and Sound Signaling – Interface Personalization and Better UX
The UCB045-RGB-CMFDV1 interface was designed with User Experience (UX) in mind – it combines touch detection with visual and acoustic feedback, creating a more intuitive and ergonomic method of operation.
RGB backlight – three LEDs combined with a diffuser evenly illuminate the entire button surface, allowing signaling in any color. This way, the user immediately recognizes the device’s status (e.g., green – active, red – alarm), which improves interface clarity and overall UX.
Sound signaling – a dedicated buzzer connector allows the addition of an acoustic signal confirming button activation. This is particularly important in noisy environments or when the user does not have visual contact with the panel. The combination of visual and auditory feedback increases confidence and reduces the risk of errors.
The combination of light and sound signals creates a coherent, multisensory interface that supports better UX by:
- improving intuitive operation,
- reducing the risk of mistakes,
- enhancing message clarity and user satisfaction.
Power Flexibility
One of the key advantages of the UCB045-RGB-CMFDV1 is power flexibility. The module supports an input voltage range from 5 to 36 V DC, making it compatible with low-voltage systems (e.g., 5 V microcontrollers), as well as with common 12 V and 24 V industrial installations, and selected 36 V applications.
Such a wide operating range allows the module to be powered directly from existing circuits, eliminating the need for additional converters and simplifying integration in various projects.
Easy Integration
The UCB045-RGB-CMFDV1 also stands out with its compact housing (45.5 × 45.5 × 5.3 mm), while the active touch area has a diameter of 16 mm – matching the dimensions of standard industrial buttons. This allows it to replace traditional mechanical solutions without the need to redesign the device structure.
The button was designed for easy integration. After mounting and connecting, only a simple program is required for it to function according to project requirements – without time-consuming calibration or complex startup procedures. Installation is also quick and straightforward: the module can be attached using high-quality 3M double-sided tape, ensuring secure fastening, e.g., to the inside of a device’s front panel. This eliminates the need for additional brackets or drilling holes – it is enough to stick the module in place. Overall, integration is intuitive and saves time both during prototyping and serial production.

Configure the Button with the Unisystem Team
We ensure that the components we deliver are precisely matched to customer needs. The UCB045-RGB-CMFDV1 module is factory-calibrated to work with protective glass about 1.1 mm thick. When using thicker glass (up to 4 mm), sensitivity may need to be readjusted to guarantee stable and precise performance. Our Solution department – Unisystem’s research and development team – provides full support in this process.
If needed, we also assist customers with integrating the button into complex systems – both on the hardware side (power, mounting, connection) and on the programming side (touch signal handling, LED backlight control). With many years of experience in designing HMI solutions, we provide a ready-to-use component fully tailored to the specifics of the application and user expectations.
Example Applications of the UCB045-RGB-CMFDV1 Button
The UCB045-RGB-CMFDV1 capacitive touch button combines reliability and precision with modern design and intuitive operation. For this reason, it can be used in:
- industrial automation – operator panels, machines, and production lines;
- medical equipment – diagnostic and laboratory devices;
- transportation – control panels, information systems, or onboard terminals;
- retail – self-service checkouts, multimedia kiosks, or payment terminals;
- automotive – multimedia systems and control panels in vehicles.
Thanks to its properties, the button is suitable for both indoor and outdoor applications. Its parameters – resistance to interference, vibration, shock, and the presence of contaminants – make it suitable even for demanding environments.
Testing Options
To simplify the evaluation of the button’s functionality, we have prepared dedicated demo kits consisting of the button, a 1.1 mm protective glass, and a cable.
