GNExB2X21 Xenon Strobe Beacon
The GNExB2X21 is an IECEx & ATEX approved explosion proof 21 Joule Xenon beacon. The robust IP66 corrosion proof GRP enclosure and extended temperature range ensures the GNExB2X21 is suitable for all Zone 1, 2, 21 & 22 hazardous location signalling applications.
The GNExB2X21 beacon produces over 900cd effective - a very high output Xenon strobe flash as required for efficient signalling in environments with elevated levels of ambient light. The optically enhanced field replaceable colour filter optimises the strobe output and is constructed from UV stable PC. The GRP enclosure features a threaded flame path, triple cable entries and a large termination area - all of which significantly reduce installation time.
