Vehicle disc horn 24V delivering 110±4dB sound output with durable black painting and robust galvanized steel body.
Vehicle disc horn 24V delivers a loud and reliable warning tone. At two meters, it produces 110±5 dB. This sharp sound cuts through heavy traffic and noisy worksites. As a result, both drivers and pedestrians receive a clear and unmistakable alert.
With a diameter of 100 mm, the horn fits well into tight spaces. The integrated bracket includes an 8.5 mm mounting hole for quick installation. Its reinforced design prevents rotation under force, which keeps the horn securely fixed during operation. These details simplify installation and improve reliability.
The housing uses galvanized steel with a black paint finish, providing long-lasting protection against rust, moisture, and dirt. A white paint seal highlights the high-side marking for added clarity. Every component, such as the flange nut, holder, gasket, and cover, supports durability and consistent performance.
Vehicle disc horn 24V operates within a wide voltage range from 20 V to 28 V. At 24 V, it consumes less than 1.5 A, making it efficient as well as reliable. The tone frequency of 415 Hz ensures recognition in any environment. Insulation resistance exceeds 1 MΩ, which confirms stable operation even in tough electrical conditions.
A life cycle test proves its long-term performance. The horn functions for 50,000 cycles with one second on and four seconds off at 26 V. Easy AMP-style connections reduce wiring time and guarantee a secure fit. These features make it a dependable choice for commercial vehicles, heavy machinery, and transport fleets.
