STExB2X21 Xenon Strobe Beacon 21 Joule
The STExB2X21 is an explosion proof 21 Joule Xenon beacon. The robust IP66 corrosion proof 316L stainless steel enclosure ensures the STExB2X21 is suitable for all Zone 1, 2, 21 & 22 hazardous location signalling applications.
The STExB2X21 beacons produce a high output Xenon flash required for effective signalling in environments with elevated levels of ambient light. The field replaceable colour filter enhances the strobe and is constructed from UV stable PC. The stainless steel enclosure features a threaded flame path, four cable entries and a large termination area - all of which significantly reduce installation time.
