GNExB2L Explosion-Proof LED Multifunction Beacon
24 VDC LED Beacon GRP

LED / Lens Option


Tomar Electronics GNExB2L is an IECEx & ATEX approved explosion proof high output LED multifunction beacon. The robust IP66 corrosion proof GRP enclosure and extended temperature range ensures the GNExB2LD2 is suitable for all Zone 1, 2, 21 & 22 hazardous location signaling applications.

The GNExB2L utilizes an array of high power Cree® LED’s, orientated to optimize 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 signaled from one device. The field replaceable color filter enhances the light output and is constructed from UV stable PC.

  • Robust, corrosion proof GRP (glass reinforced polyester) enclosure
  • Ingress protection IP66
  • Automatic synchronisation on multi-beacon systems
  • Choice of five flash rates1Hz, 1.5Hz, 2Hz, double and triple flash.
