BR 50 Series

BR 50 Signal Tower

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.

Series BR 50 Features:

  • Modular design with sturdy housing for all indoor and outdoor applications in tough conditions.
  • High protection system IP 54 (optionally IP 65).
  • Monitored module for greater safety; the light bulb has two separate LED strands. If one strand fails, the alarm contact is activated and the second strand continues to light.
  • Shock and Vibration Tolerant (LED or Xenon)
  • UL Listed

The Rugged Choice for Industrial Machinery Status Indication

Appealing Design

54 mm diameter complements industrial machinery while offering excellent visibility.

Modular Design

Modular design with 6 different color elements and 4 mounting methods offers endless combination possibilities.

Visual

The light is amplified by the internal prisms of the impact-proof,heat-resistant and dust-proof polycarbonate lens and can be easily identified from all sides.

IP 54 / IP 65 enclosure rating

Standard indoor version can be easily upgraded for use in outdoor applications and washdown requirements with optional o-rings.

Versatile mounting option

Tubular stand or bracket with various tube lengths, or direct to enclosure.

Self-monitoring module

Integrated functional fault monitoring with redundant LED array and dry contact relay supports automatic switchover to secondary LEDs and remote fault notification.

AS-I BUS module

Simple Integration to the AS-i interface BUS system for up to 4 stages or 62 master/slave connections.

Stable structure

Mechanical and electronic components are uncoupled, resulting in a more stable structure that is less sensitive to vibration.
