BExBG21 Flameproof Xenon Beacon (21 Joules)

$1,660.69 $1,845.21


TOMAR Electronics flameproof BExBG21 Xenon beacons are suitable for Zone 1, 2, 21 & 22 applications. Approved to IECEx, ATEX, Ex EAC and INMETRO standards. The BExBG21 21 Joule beacons robust construction enables installation in the harshest of environments.

The BExBG21 has three distinct user select-able flash patterns and for units with DC operating voltages a second stage flash pattern can be selected remotely. Additional features include a stainless steel guard and stainless steel mounting bracket as standard. The BEx range features enclosures manufactured from corrosion proof, marine grade copper free LM6 aluminum with a chromate and powder coat finish. All models have two M20 cable entries, large termination areas containing in & out terminals and an ingress protection of IP66/67.

  • Marine grade, corrosion proof, LM6 aluminum enclosure
  • Automatic synchronization on multi-beacon system.
  • Beacons can be set to ‘flip-flop’ alternating mode with other units on multi-beacon systems.
  • Xenon tubes mechanically secured against shock & vibration
  • Glass lens & Stainless Steel guard standard
  • Very large termination area.
  • Dual M20 cable entries – adapters available.
  • Stopping plug included.
  • Ratchet adjustable stainless steel ‘U’ bracket.
  • Reverse polarity diode fitted.
  • IP66/67 ingress protection.
  • 520 candela effective light intensity.
  • UV stable PC, field replaceable, color lens filter.
