E2S STExB2X21 explosion-proof 21 Joule Xenon Strobe Beacon
The E2S STExB2X21 is an explosion-proof 21 Joule Xenon Strobe Beacon.
The E2S STExB2X21 is an explosion-proof 21 Joule Xenon Strobe Beacon. The robust IP66 corrosion proof 316L stainless steel enclosure ensures this Beacon is suitable for all Zone 1, 2, 21 & 22 hazardous location signalling applications.
The STExB2X21 Beacon produces a high output Xenon flash required for effective signalling in environments with elevated levels of ambient light. The field replaceable color filter enhances the strobe and is constructed from UV stable PC. The stainless steel enclosure features a threaded flame path, 4 cable entries and a large termination area – all of which significantly reduce installation time.
