8WD4 signaling columns

Signaling columns are important optical aids for supervising complicated workflows on machines or in automated processes. In emergency situations, they serve as a visual or acoustic warning system. Thanks to their modularity, the steady, blinking, flashing and all-round light elements, as well as buzzer and siren elements can be flexibly designed and used in a great many ways. They are easy to install and extremely resistant to shock and vibrations.
