Stack lights

Stack lights for control and safety

Stack lights, also known as signal towers, are used in any industrial sector to draw the attention to statuses by means of an acoustic or optical signal. In dangerous situations they are used as visual or acoustic warning, thus providing safety.

Stack lights are available as complete devices or as user-friendly modules that can be individually combined. That means that there is a suitable signaling device for every application, customizable through various combinations of the visual and acoustic signalling elements. Each color can be assigned its own meaning that may be defined individually for every application.

Versatile applications

Signaling devices are of course used in almost all sectors of industry, whether as status indication, control lights in automated processes or warning signals in emergencies. Below are some examples of signal tower applications:

  • Machine tools
  • Production lines
  • Test stations
  • Gate access

Stack lights can be used reliably on an international level, as well as in harsh environments and difficult lighting conditions. The variety of modules ensures flexible mounting.
