Harmony XB5 double push button head flat/flat white/black with self-return plastic ZB5AA7121

Double button – reliability and versatility in control

This double button from the Harmony XB5 series is a robust solution for controlling machines and devices. Designed for both professional installers and end-users, it combines durability, ease of installation, and configuration flexibility. Made from high-quality thermoplastic, it is resistant to harsh industrial conditions and ensures long-lasting reliability.

Design and application

The button features a flat profile and a black and white finish for clear function identification. With a 22.5 mm mounting hole diameter, it is compatible with a wide range of control panels. The self-resetting design ensures immediate reset after pressing, and the presence of printing facilitates function labeling. It is ideal for applications requiring frequent circuit switching, such as controlling motors, valves, or signaling the operating status of machines.

Advantages and benefits

• Modular design: enables easy assembly and replacement, as well as flexible adaptation to individual application needs.
• Durability: the thermoplastic housing provides resistance to impact, dust, water, and vibration.
• Versatility: can be used in various industrial environments thanks to high degrees of protection (IP66, IP67, IP69K).
• Readability: clear colors (black and white) and the presence of printing minimize the risk of errors during operation.
• Easy integration: compatible with a wide range of contact blocks and other elements of the Harmony XB5 series.
• Safety: the button meets the requirements of many standards (IEC, UL, CSA, CE), which guarantees safe operation of the device.
• Simple installation: snap-in mounting allows for quick and easy installation and replacement of the button.

Design features

The button head is made of high-quality plastic, providing it with lightness and corrosion resistance. The front ring, also made of plastic, adds aesthetics and protects against mechanical damage. The rectangular shape of the lens improves the visibility of the button even in difficult lighting conditions. The lack of backlighting allows for reducing power consumption and simplifying the control circuit design. The use of self-resetting technology eliminates the need to manually reset the button after pressing – this saves time and increases operator efficiency.
