Setting new standards in signaling: SmartLight signal towers

More visibility, more control, more impact – with SmartLight Black Line signal towers

SmartLight signal towers

With the new SmartLights, Balluff expands its portfolio with a powerful signal tower for demanding industrial applications. It is designed specifically for situations where information must be seen quickly, clearly and reliably – even from a distance.

Benefits of SmartLight Black Line signal towers at a glance

Specially in dynamic or complex systems, signals must be clearly visible, easy to understand and simple to control.

SmartLight Black Line supports this with high visibility, direct control and the flexibility to adapt signals during operation.

Signals that remain clear, even in challenging conditions or over long distances.
Existing systems can be expanded or upgraded with ease.
Even complex or changing states can be displayed clearly.
Signals can be linked directly to real process data and adjusted quickly.

Advanced signaling for demanding processes

High visibility is the basis of effective signaling. Even over long distances or in intense ambient light, signals from SmartLight Black Line products remain clearly visible and support reliable status assessment. With integrated StrobeLight, SmartLight signal lights extend classic signaling with a highly noticeable light pulse. This helps operators detect critical conditions faster, regardless of ambient noise or the visual complexity of the environment. 

Another new feature is Ultimate mode. It enables direct signal control via process data and reduces parameterization effort compared with Flex mode. This gives you more flexibility and brings signaling closer to the process. Integration into existing systems is just as straightforward. Extended operating modes and compatible settings support easy integration into both new and existing installations. 

Typical applications for SmartLight signal lights

SmartLight Black Line products are especially relevant wherever clear and instantly understandable signals are critical: 

  • Machines and systems with complex or frequently changing operating states 

  • Production lines with high throughput and short response times 

  • Safety-critical processes where delays increase risk 

  • Large-scale installations where signals must remain visible over longer distances 

  • Retrofit scenarios where existing signaling needs to be modernized 

Who are SmartLight Black Line products designed for?

SmartLight Black Line products are designed for users who need more than a classic status display. 

They are designed for applications with high demands on visibility, ease of use and process integration. Wherever signaling supports process reliability and efficiency, they offer clear advantages.
