Industrial Ethernet connector aids port security
The RJ-Lnxx from Aerco is industry's first IP67 sealed RJ-45 connector that extends Ethernet from boardroom to the factory floor.
To prevent equipment becoming 'live', surge arrestors connected to a grounding network are used to dissipate dangerous current.
Similar to components used to block lightning surges on antenna lines for cellular base stations, PolyPhaser's DSX series filter is installed on RF and data inputs on communication equipment in the vicinity of the track.
The design of the component circuitry has been optimised to respond quickly to dangerous overvoltage, while allowing the communications systems to operate connected to their normal power supply.
The DSX surge product design and operation has been accepted by the Italian rail authorities, and is already installed protecting the lives of maintenance workers on many types of track including high-speed lines.
The filter series will no doubt have further success in other European rail markets.
