The TL 305 series of tower lights with aluminum housing from Lueze offers clearly visible light signals as well as an optional IO-Link interface. The compact towers are available preconfigured with three, four or five segments. The new range of tower lights includes the TL 305 models with predefined color assignment as well as the TL 305-IOL models with IO-Link interface. The IO-Link variants allow different operating modes and provide an extensive selection of colors. On request, the tower lights are also available with an acoustic signaler. The M30 thread and M12 connector along with matching accessories simplify installation. If fast commissioning is required, users can actuate eight predetermined or user-defined configurations via the three external trigger inputs even without IO-Link connection.
