Pfannenberg  Series BR 50 stack lights provide convenient visual indication for status, alert, and alarm as well as audible warning of machinery operating condition or process status. The easy-to-assemble component architecture supports up to five interchangeable modules. Choice of modules include bright LED and filament lamps for continuous or blinking operation, and hi-visibility flashing xenon tubes. The horn sounder module supports audible alarming to complement visual warnings that may go unnoticed.

Stack lights are generally installed onto electronic control cabinets, machinery frames, junction boxes, or walls. Several mounting options are available including direct-to-base, tube-and-bracket, and tube-and-stand (plinth). An optional wall-mount bracket supports the tube-and-stand mount for an attractive look.

Pfannenberg’s Series BR 50 stack lights are the smart signaling choice for machinery status indication, checkout lane availability, automated process monitoring, upset condition alarming, and many other requirements.
