Strong penetrating sound, a typical warning alarm sound used to indicate reverse movement of vehicles. Sirens SAP-1302 series meet all requirements for the industry and transport segment.
The penetrating "strength" and overall audibility of a given sound depends on various factors.
One of the most important ones is frequency, sound level (volume), type of sound (continuous, intermittent, sweep) and also the overall noise in the given environment (from traffic, machines, people).
Some typical tones have proven to be very easily audible over the years, even in very noisy environments. Naturally, that is why many vehicles produce more or less very similar sound for warning at the reverse movement.
Typically those are low frequencies in a range of approximately 1000 -2500 Hz. That's also why Sonitron, one of the world leaders in piezo technology, produces its SAP-1302 series with these frequencies and a typical intermittent sound (1Hz).
Usually, the SAP-1302 series are installed at the back of a car, truck, tractor, jeep, golf-trolley, ... or any other vehicle that can move in reverse at any moment, thus alerting people approaching the vehicle.
The quality, longevity and reliability are key factors at production; the SAP series are tested for use under all weather conditions IP67 and have a lifetime in continuous use of more than 1000 hours.
There are 4 basic versions of sirens available, differing in the frequency of the sound as well as its volume:
For easier use, Sonitron offers different connection versions, either with fastons or with a cable:
Our assortment offers a wide range of sirens for all areas of use, from hobby projects, through use in industry, transport but also in medical devices.
Features / Benefits of SAP-1302 sirens:
- Very low current consumption (typically 65-145 mA @ 12V)
- Dust-tight, shock and water-resistant (IP67)
- Low frequency (large travelling distance of audible wavelength)
- No magnetic field (EMC)
- Robust fibre reinforced PBT housing
- The high lifetime in continuous function
- Easily mountable design
- Multi-voltage application (12/24/48Vdc)
