CTE50 economical signal towers combine one to five LED layers with optional audible indication. Select a fixed color stack, steady or flashing light operation, an appropriate supply version and one of four mounting arrangements.
The SMD LED construction uses prism-pattern PC lenses and an ABS base. High-brightness LED components have a typical life reference above 50,000 hours; this is a component reference rather than a complete-assembly service-life guarantee. Color combinations are fixed selections and cannot be freely rearranged.

For example, CTE50-RYG/ASB-A10L06 is the three-layer disc-mounted 24VAC/DC model with intermittent sound. CTE50-RYGBW/BSM-DL06 is the five-layer circular-folding 220VAC model with continuous sound.

These are color-channel references. DC power is calculated from nominal voltage and maximum current, then rounded. AC power and current remain separate specifications; complete-stack consumption depends on the selected configuration.

Individual external contacts switch the layer and sound circuits. Follow the supply and polarity arrangement for the selected version. An open mode jumper selects flashing; a fitted link selects steady illumination.
Release a lens module by rotating counterclockwise to align the marks and pulling upward. Assemble it by aligning the marks, pressing downward and turning clockwise until the triangular mark reaches the index.
The cable outlet must not face upward. Install regular IP43 versions upright and vertical because their water protection is below IPX4. Use the hole pattern and fixing hardware for the chosen bracket, tighten the mounting and protect the wires against impact and abrasion.
Disconnect the supply before installation, wiring, work on the assembly or maintenance. Verify the model and rated voltage, prevent conductive dust or liquid from entering, and have qualified personnel handle complex faults and high-voltage components.
Use these products for industrial signaling. High-reliability infrastructure, personal-safety functions, harsh environments, fire or explosion hazards, military uses and aerospace projects require a specifically designed and expressly confirmed configuration.
