Stack Lights or Signal Columns

Siemens signaling columns provide visual and audible alerts, feature a modular design, are easy to install, and offer robust resistance to shock and vibration.

The Siemens portfolio of stack lights and signaling columns consists of industrial tower lights and acoustic warning devices. Use them to monitor complex workflows on machines or in automated processes, and as visual or acoustic warning systems in emergencies.

Complex industrial environments require clear, adaptable signaling for process control and safety. Our signaling columns offer modularity and flexible design. Customize visual and acoustic elements to meet your needs, ensuring clear communication and rapid response to operational changes or emergencies.

Enjoy easy installation and high resistance to shock and vibration for reliable operation in industrial settings. Integrate with AS-Interface or IO-Link for digital connectivity and diagnostics to enhance process control.

Monitor complex processes on machines and automated processes using clear visual aids. Use our signal towers as visual or audible warning systems in emergencies to improve operational safety.

Install our signal columns and stack lights with ease. Multiple components can be mounted between the connector and the cover.

Deploy signaling columns in industrial and building applications, such as assembly lines, conveyor systems, and shipping stations. Their robust design withstands shock and vibration, ensuring reliable performance and a long service life.

The 2-inch 8WD42 signal columns feature modular stack lights. Configure steady, blinking, flashing, or all-around light elements. They have an IP54 protection rating, and the adapter includes AS-Interface.

The 8WD44 signaling columns, with a 3-inch diameter, offer an IP65 protection rating, and up to five elements can be mounted between the connection element and the cover. The adapter element includes AS-Interface, IO-Link, and an M12 connector.

The new compact 8WD46 signal towers offer flexible settings for light color, intensity, and function. Choose from steady, flashing, blinking, or rotating lights and level indicators. Control via conventional 24V (USB) or IO-Link.
