This is precisely the advantage that the "Ahead Door Shows" exploits: A projector installed above the elevator door projects news and advertisements onto it, helping users pass the time while they wait. The content is provided from a central location, the Ahead Content Management System, to the projectors, which are networked across the individual floors via ETHERNET.
However, this connection is the difficult part. "Since this involves a retrofit, it needs electricity from somewhere," says Claudio Haas. "In an elevator shaft, it's not like at home, where you can just look for an available outlet - it requires a secure, professional connection to the elevator system."
And that's exactly what the WINSTA® Pluggable Connection System, with protection against mismating, offers. In a convential connection approach, installers would have to unwind the line from a cable drum, cut it, insulate and crimp the conductors and finally connect them to the "Ahead Door Show."
With WAGO's solution, all they have to do is go from floor to floor and plug in the preassembled four meter cables - no tools required. The risk of dropping a wire stripper or screwdriver into the shaft never even arises. Tool-free connection also prevents injuries.
