BExBG05 Xenon Beacon
The flameproof BExBG05 Xenon beacons are suitable for Zone 1, 2, 21
& 22 applications.
The BExBG05 5 Joule beacons are ideal for eneral si nallin duties whilst their robust construction makes installation
in the harshest of environments possible. Additional features include automatic synchronisation on multi-beacon systems
and stainless steel uard and mountin bracket as standard.
The BEx ran e features enclosures manufactured from corrosion proof, marine rade copper free LM6 aluminium which is
phosphated and powder coated. All models have two M20 cable entries, lar e termination areas containin in & out
terminals (Ex de version only) and an in ress protection of IP66/67 (Ex d) and IP66 (Ex de).
Features:
•Automatic synchronisation on multi-beacon system.
•Beacons can be set to ‘flip-flop’ alternatin mode with
other units on multi-beacon systems.
•Xenon tubes mechanically secured a ainst shock
& vibration
•Glass lens & Stainless Steel uard
•Very lar e termination area.
•Ratchet adjustable stainless steel ‘U’ bracket.
•IN & OUT terminals (Ex de version only).
