The Werma 645.840.55 is a clear (colorless) LED beacon module with TwinFLASH functionality from the KombiSIGN 71 series, engineered for high-visibility status indication in automation and industrial environments. Its transparent housing allows the color of the inserted light source to be customized or used for neutral signaling. Powered by 24 V AC/DC, it utilizes energy-efficient LED technology and delivers an alternating double-pulse flash pattern (TwinFLASH) that ensures enhanced visibility, especially in noisy or visually congested settings. The Ø70 mm polycarbonate lens is impact-resistant, and the IP65 protection ensures resistance to water jets and dust. With tool-free twist-lock mounting, it integrates seamlessly into modular KombiSIGN 71 signal towers.
