Overview
The Werma 641.100.00 red light element is a modular, continuous illumination component engineered for the KombiSIGN 71 stacklight series. This permanent light element delivers reliable status indication across industrial automation, machine control, and facility safety systems. With its broad voltage range and weather-sealed design, the 641.100.00 integrates seamlessly into existing signal tower installations, providing visual operator feedback under diverse operating conditions.
Key Features
- Wide voltage compatibility: Operates on 12–230V AC/DC, eliminating the need for multiple SKUs across different installations
- Integrated B15d lampholder: Accepts standard incandescent bulbs; lamp sold separately
- IP65 protection: Sealed against water spray and dust ingress; suitable for washdown and outdoor environments
- Compact modular design: 70mm diameter, 66mm height; stacks with other KombiSIGN 71 elements for multi-color tower systems
- Extended temperature range: Rated –20°C to +50°C for harsh industrial climates
- RoHS compliant: Meets environmental and electrical safety standards
