Electromechanical horn S70

Sound for greater safety: Signal horns are required in vehicles by law so that other road users can be made aware of dangerous situations in a clearly audible manner. With its full sound, the HELLA S70 horn is particularly suitable for commercial vehicles. It generates maximum attention with its high sound pressure level.

 

The S70 horn is operated by the battery current or a control current coming from the steering wheel. This is passed through a relay to generate a voltage dip-free control current. The control current activates the electromagnet of the signal horn. This in turn attracts a metal core or armature, and above it, the steel diaphragm of the horn. The sound is produced by interrupting the power supply when the diaphragm is tightened and the armature and diaphragm return to the original position.

 

The HELLA S70 horn is available with a high (420 Hz) available, wit ha operating voltage of 12 V and produces a sound pressure level of approx. 112 dB(A) at 2 m distance.
