Slotted Microwave Guide Mini (SMGM)

Digitalization and Industry 4.0 are transforming industrial environments. From automated shuttle systems to AS/RS stacker cranes and EMS conveyors, modern facilities generate increasing volumes of control, diagnostic and safety data that must be transmitted reliably and in real time.

Traditional conductor-based communication systems with low transmission rates are often no longer sufficient for complex automation environments. At the same time, free radio solutions require careful frequency planning and may be affected by interference in industrial settings. 

The Slotted Microwave Guide Mini (SMGM) from VAHLE is designed specifically for high-speed, interference-free industrial data transmission. Communication occurs within a shielded aluminum slotted waveguide profile, eliminating electromagnetic interference and preventing influence on surrounding wireless systems.

Due to its extremely compact design, the SMGM can be easily integrated into almost all common EMS profiles and conveyor systems without extensive configuration. 

Interference-Free Data Transmission in Shielded Aluminum Profiles

The SMGM data transmission system enables secure, high-performance communication for:

• Automated shuttle systems
• AS/RS stacker cranes
• Standard and process cranes
• Sortation and conveyor systems
• Heavy-duty crane applications (indoor use)
• Dark rides and automated attractions
• Elevator and vertical transport systems

By transmitting data inside a shielded slotted waveguide, the SMGM ensures:

• Stable communication in high-EMI environments
• No disruption of nearby wireless networks
• Reliable real-time control signal transmission
• Secure communication for safety-critical applications

This makes it ideal for indoor automated systems that require high availability and predictable performance.

Designed for Industry 4.0 & System Integration

The SMGM was developed to meet the growing data demands of Industry 4.0 environments. It supports seamless integration into automation architectures and industrial communication networks.

Key integration features include:

• Plug-and-play installation
• Compatibility with PROFINET and PROFIsafe
• High compatibility with VAHLE busbar and control systems
• Coexistence with existing wireless systems
• Integration with VAHLE vPOWER (energy), vPOS (positioning) and vDRIVE (control)

When combined with VAHLE’s modular electrification and positioning technologies, the SMGM becomes part of a complete system solution for mobile automation.
