Description:
A 12VDC Horn is an electronic device that produces a loud, distinctive sound when activated by a 12-volt direct current (DC) power source. It includes a diaphragm, an electromagnetic coil, and a set of contacts. When the horn button is pressed, it sends a 12VDC current to the coil, which creates a magnetic field that pulls the contacts together. This completes an electrical circuit that sends current through the diaphragm, causing it to vibrate rapidly and produce a loud, audible sound.

Attributes:
• Designed to be durable and long-lasting.
• Sound frequency is 350 Hz.
• Provided with one mounting hole of diameter 8.5mm.

Applications:
A 12VDC Horn is a critical safety feature, helping to warn other drivers or pedestrians of the vehicle's presence or impending movement. Mostly used in CAT 416, 426 F2, 428, 426, 42, 420, 430, 432, 434, 444, 420XE, 424, 415, 440, and 450 Backhoe Loaders.
