Systems for optimising production
In addition to classic signalling devices, WERMA offers networked solutions for process optimisation, which provide an important approach to increasing efficiency, productivity and quality. Our solutions are plug and play and easy to retrofit, because WERMA takes signalling technology to the next level.
Support and secure processes with intelligent signal technology
Optical and acoustic signalling elements can be flexibly combined in the modular signal towers, also known as stack lights, just as you need them. The modular design also allows additional elements to be retrofitted at a later date. The signal tower or stack light elements are mechanically and electrically connected in seconds using the bayonet catch.
Pre-configured signal towers from WERMA can be ordered as a compact unit with just one article number, which reduces your ordering and installation workload. They impress with their attractive design, versatile mounting options and can therefore be used in a wide variety of areas.
Configurators
Configure signalling devices based on colour, light effect, acoustics and compatible mounting accessories. The system allows precise product customization.
