Otennlux

Overview
The OLA2-301 series is a proven aluminum-bodied signal tower light engineered for CNC machines and industrial equipment. Available in 24V or 100-277V versions. Standard 3-color configuration (red, yellow, green); other color counts and buzzer options available.

Key details

• 3-color aluminum tower light (red, yellow, green) — selectable 1/2/3/4/5-color versions
• Installation: foldable, straight or extended straight
• Optional buzzer (Yes/No)
• Connection: cable or M12 connector
• Lamp body diameter: 50 mm
• Voltage: 24V or 100-277V
• Warranty: 3 years

Design & optics

• Efficient LED multi-signal modules offering competitive brightness and low power consumption
• Mixed-prism lampshade eliminates visual blind spots and improves long-distance visibility
• Double-mirror structure enhances light propagation and color distinction with minimal LEDs
• Modular LED assembly allows rearrangement or addition of modules post-installation without rewiring
• Transparent PC tube with linear chip arrangement for corrosion and high-temperature resistance

Electronics & reliability

• Imported long-life capacitors for stable power performance
• Aluminum PCB for effective heat dissipation and reduced lumen depreciation
• High-lumen SMD2835 LEDs (~50,000 hours) delivering bright, non-flickering light

Applications
Spectral equipment, laser equipment, food filling machines, ceramic machinery, automated warehouses, HMI and similar machine-tool environments.

Certifications / Compliance
CE / RoHS / UL / ETL / CCC / Anti-Explosion (certifications vary by model/configuration).
