Slotted Microwave Guide Xtreme (SMGX)

In ports, on open industrial sites or in amusement parks, technical applications are exposed to various weather influences. To ensure reliable and safe operation of crane systems or amusement rides, power and data transmission systems have to withstand all the rigors of the weather.

With the SMGX (Slotted Microwave Guide Xtreme) data communication system, VAHLE has adapted the proven SMGM system for outdoor use.

It is based on the functional principle of the SMGM system, but has particularly robust mechanical components and also ensures significantly higher tolerances. The shielded slotted microwave guide enables high transmission rates and avoids unwanted interference signals from or to the outside. The system can also be used in indoor installations and its optional heating system ensures outdoor wall applications under extreme conditions.

Like its sister product, the SMGX system can be combined with the proven VAHLE conductor system without extensive configuration.

By combining it with the modules for energy supply (vPOWER), positioning (vPOS) and drive control (vDRIVE), it is available as a system solution. The comprehensive SMG service tool can also be used here, allowing users to analyze the system and adapt it if necessary.
