RS PRO Black Single Tone Electronic Sounder, 12 to 80 V DC, 107 dB at 1 m

This single-tone electronic sounder from RS PRO generates 107 dB of sound to let you know when you're within one metre of an object. The warning tone is loud enough to be heard over the sound of machinery or automobiles, making it a good choice for alarm applications in vehicles and factories.


The alarm casing is made of tough, glass-filled nylon to withstand knocks and scratches effectively. The sounder is also completely waterproof and pressure-washable, so it won't be damaged by rain or mud. This makes it suitable for both on-road and off-road vehicles.


This electronic sounder is safe to use in all weather conditions and can withstand temperatures ranging from -30°C to +70°C. This device is commonly used in passenger cars as well as cargo vehicles in farms, warehouses and quarries.
