The 8WD4408-0AA serves as the base connection element for Siemens SIRIUS 8WD4 signaling columns (70 mm diameter), providing secure pipe mounting capability for stackable tower light systems used in machine status indication, alarmy, and process visualization. It includes an integrated cover lid and seal to maintain the Stopień ochrony IP65 when mounted outdoors or in washdown environments, protecting internal wiring from dust, water jets, and mechanical impact.
This accessory uses screw-type terminals for reliable electrical connections to light elements, buzzers, or AS-i interface modules above it in the signaling column stack. The 70 mm outer diameter matches standard SIRIUS 8WD44 signaling column elements, enabling modular assembly of continuous, flashing, or rotating beacons in 24/115/230 V AC/DC configurations. Its compact 42.5 mm height × 70 szerokość mm footprint keeps the overall tower height minimal while providing robust mechanical support for pipe lengths up to 400 mm or longer when paired with appropriate single/double pipe feet.
Designed per DIN EN 61346-2 equipment marking standards, the 8WD4408-0AA operates reliably from -20°C to +50°C ambient temperature and carries approvals including CE, ul, and CSA for global industrial applications such as manufacturing lines, przenośniki, assembly stations, and process control panels. It works seamlessly with SIRIUS accessories like angle brackets (8WD44 08-0CC), designation plates, and single/metal pipe feet for flexible wall, floor, or pipe installations.
