E2S BExBG21DP Explosion Proof Beacons

E2S BExBG21DP Explosion Proof Beacons


E2S BExBG21DP Explosion Proof Beacons for Hazardous Area Signalling Applications

The 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 selectable 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 aluminium 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.
