Use this yellow flashing beacon from WERMA as part of a signal tower for enhanced safety in your workplace. It's equipped with a bayonet fixing that allows you to twist it into place for quick and easy assembly. You can stack it with both optical and audible elements from the KombiSIGN 71 series for enhanced versatility. Thanks to its low operational current of 30mA, this beacon is an energy-efficient choice. Its long optical service life of at least 50,000 hours means it won't need frequent replacement.

• O-ring provides optical isolation to prevent illumination of the adjacent unit
• Broad operating temperature range of -20°C to +50°C for use in harsh environments
• IP65 (ingress protection) rating means it's protected against dust and low-pressure water jets
• Light weight of 59g to ensure minimal strain on your equipment

• Factory floors
• Construction industry
• Industrial automation

You can stack up to five elements onto a base, allowing you to build a signal tower that meets your specifications.
