The Harmony XV6 series of modular signal towers, which can be individually configured, are visual and acoustic signalling devices that reliably indicate the operating processes or conditions of a machine or application. In addition to their modern design, the signal towers with a 60-mm diameter are characterised by energy-saving LED technology with optimum brightness, which enables an excellent 360° visibility. Thanks to its simple, tool-free installation, the robust XV6 signal tower (up to IP65) is suitable for many different applications and use in harsh environments.
