Rotating beacon STExB2RT1

halogen115VAC12VDC

Product Overview
The STExB2RT1 is an explosion-proof rotating halogen beacon designed for signalling in hazardous locations (Zones 1, 2, 21 & 22). The enclosure is corrosion-proof 316L stainless steel, suitable for demanding industrial environments.

Description
The STExB2RT1 provides a high-output rotating signal for visibility in high ambient light. It uses a field-replaceable UV-stable polycarbonate colour filter and a high-impact borosilicate lens. The 316L stainless steel enclosure features a threaded flamepath, four M20 cable entries, duplicate terminations for daisy-chain installations and a large termination area to simplify wiring.
