Compact and Robust Design

EBRO SBUs are engineered for direct mounting on pneumatic actuators according to VDI/VDE 3845 standards. Their compact footprint allows space-saving installations, while the robust aluminum housing provides protection against mechanical damage and harsh environmental conditions. A powder-coated finish adds corrosion resistance, ensuring durability in demanding industrial environments.

  • Microswitches and sensors: SBUs are equipped with 2 or 3 microswitches or proximity sensors for precise valve position monitoring. Optional mid-position detection is available for complex applications.
  • Spring terminals: Color-coded spring terminals simplify wiring and ensure secure and reliable connections for sensors and solenoid valves.
  • Integrated PCB: Facilitates direct connection of switches and solenoids, simplifying installation. Terminal markings and an integrated wiring diagram enhance usability.
  • 360° position indicator: Provides visual feedback of valve positions, including OPEN/CLOSED and intermediate states, supporting efficient system operation.
  • Diagnostics and feedback: Advanced models, such as SBU IO-Link, support digital position detection, wear-free monitoring, and real-time diagnostics, enabling proactive maintenance and system reliability.
  • Acceleration sensor: In premium models, additional sensors monitor vibrations, providing insights into process flow anomalies and ensuring optimal system health.

SBUs offer direct and bracket mounting options, making them compatible with a wide range of pneumatic actuators. The modular design supports configurations with microswitches, proximity sensors, or a combination, tailored to application requirements. Adjustable switch cams allow customization of operating angles up to 240°.

  • Ingress protection: SBUs are rated IP65, IP67, and IP68, offering excellent resistance to dust, water, and contaminants, ensuring long-term reliability in challenging environments.
  • Optional ATEX certification: Guarantees safe operation in explosive atmospheres.
  • Secure fasteners and durable sealing: Fixed screws and NBR or silicone seals prevent component loss and provide effective environmental sealing.
  • IO-Link compatibility: Models like SBU IO-Link enable seamless integration into Industry 4.0 frameworks, allowing parameterization and diagnostics via IO-Link or the “EBRO Plus” app.
  • IoT-ready: With Bluetooth and optional IoT connectivity, SBUs can transmit real-time operational data, enabling advanced process monitoring and optimization.

SBUs support up to two solenoid valves with independent or combined control options. Advanced designs allow a third switch or additional solenoid connection, providing flexibility for complex system configurations. Some models include optional solenoid plugs with LED indicators and protective circuits.

EBRO SBUs are designed to operate in ambient temperatures from -20°C to +70°C. Special designs are available for extreme conditions, ensuring consistent performance in diverse industrial applications.

Conclusion

The SBU switch boxes from EBRO Armaturen offer a powerful combination of advanced features, durability, and flexibility. With a compact design, high protection rating, and intelligent monitoring capabilities, SBUs set the standard for actuator control and diagnostics.

Whether for simple OPEN/CLOSED monitoring or complex IoT-integrated applications, EBRO SBUs provide unmatched reliability and performance, making them an essential component for modern industrial systems.
