STExB2LD2 Explosion Proof LED Multi-function Beacon

The STExB2LD2 is an IECEx & ATEX approved explosion proof multi-function LED beacon. The robust IP66 corrosion proof 316L stainless steel enclosure ensures the STExB2LD2 is suitable for all Zone 1, 2, 21 & 22 hazardous location signalling applications.

The STExB2LD2 utilises an array of high power Cree® LED's, orientated to optimise visibility in any direction. The beacon can be configured as a steady beacon for status indicator use, with a light output of up to 174 candela. Alternatively one of the five flashing modes, with a light output of up to 338 candela, may be used for warning applications. DC voltage versions feature three remotely selectable stages enabling multiple warnings to be signalled from one device. The field replaceable colour filter enhances the light output and is constructed from UV stable PC.
