The Eaton M22-DH-R pushbutton belongs to the RMQ-Titan range and is designed as a single unit. It features an extended design and is constructed with a tactile mechanism, providing a clear tactile feedback when operated. The button faceplate is red and unlabelled, allowing for individual labelling or identification. The front ring is made of titanium, ensuring a robust and corrosion-resistant surface. The front dimensions are 22 mm × 22 mm, making it suitable for standard mounting openings in enclosures and control panels.

Pushbutton is the core function of this device, with the extended design enabling better accessibility and clearer operation. The red faceplate serves as a visual indicator, typically used for start or warning functions. The unlabelled version allows for flexible use, as labelling can be applied according to specific application requirements. The titanium front ring ensures high mechanical stability and resistance to external influences such as corrosion or mechanical stress.

Protection rating IP66, IP67, IP69K indicates the high protection class of the device. IP66 means dust-tight and protects against powerful water jets from any direction. IP67 also ensures dust-tightness and protection against temporary immersion in water. IP69K provides additional protection against hot steam and high-pressure cleaning, making the device suitable for use in the food industry, chemical industry, or environments with high cleaning requirements. These protection ratings make the pushbutton suitable for outdoor use as well as industrial environments with high demands on environmental resistance.

The pushbutton is designed for connection to SmartWire-DT, enabling integration into decentralised control systems. The connection is made via RMQ-SWD connectors, ensuring secure and reliable signal transmission. The standards IEC/EN 60947 and VDE 0660 are complied with, confirming adherence to international and national safety and functional standards for switching devices. These standards include requirements for electrical safety, operational reliability, and mechanical durability.

Compatibility and accessories include various components that extend functionality. These include contact elements such as M22-K01 (1NC front) or M22-K01D (1NO1NC front), used for different switching functions. Button accessories such as M22S-ST-X93 (label holder I 0 II 2) or M22S-ST-F10 (holder+label ARRET MARCHE) allow for labelling and identification of the button. Mounting components such as M22-XE5 mounting plate or M22-E1 single mounting plate facilitate installation. The M22-H4 cap or M22-H1 cap offer additional protection and visual distinction. Other components such as M22S-ST-GB12 (label holder MAN 0 AUTO) or M22-SWD-KC11 sensor 2 positions changeover switch expand application possibilities in complex control systems.

Installation is carried out in standard 22 mm openings in enclosures or control panels. Mounting plates and fixing plates simplify installation, especially when multiple devices are mounted in a row. The pushbutton is designed for use in industrial control systems where high reliability, mechanical robustness, and resistance to environmental influences are required. The use of plastic as housing material ensures sufficient mechanical stability while keeping weight low. Dimensions are 29.7 mm (width), 35.4 mm (depth), and 29.7 mm (height), defining the installation size within the enclosure.

Operational advantages include the high protection class, enabling use in demanding environments, and compatibility with SmartWire-DT systems, allowing flexible integration into modern control systems. The robust construction with titanium front ring and plastic housing ensures long service life and low maintenance requirements. The unlabelled button faceplate offers flexibility in identification, while the extended design ensures safe and unambiguous operation. Compliance with standards IEC/EN 60947 and VDE 0660 ensures electrical and mechanical safety during operation.
