Sound emitters manufactured by Sonitron

Sonitron is a leading manufacturer of piezoelectric acoustic components founded in 1977. The company's products are widely in demand in various applications: security and fire alarm systems, video surveillance, emergency notification, agricultural machinery and transport, medical equipment, games and toys, sound alarms, commercial equipment, industrial control and management systems.

The assortment of the company "CHIP and DIP" includes the most popular series of piezo emitters Sonitron.

SMA series

The SMA series is the most versatile sound transducer series, specifically designed to meet the widest requirements for sound pressure, dimensions and mounting methods. The emitters contain a built-in driver-oscillator, due to which the emitter requires only a direct current source with a voltage of 1.5 to 24 V. The SMA series sound emitters produce a clear tone signal at an operating frequency of 3-3.8 kHz (depending on the model).

SMA Series Sound Emitters

SMA sounders are available in five sizes: 13mm, 17mm, 21mm, 24mm and 30mm. Two versions are available for lead and surface (SMD) PCB mounting.

PIN version

SMD version, for surface mounting

Peculiarities:

• Octagonal shape;
• Lightweight monolithic construction;
• The front panel is impact resistant and impervious to water and dust;
• Low power consumption;
• No radiated electromagnetic fields.

SMAT Series

The SMAT series are piezo emitters without a built-in driver; an external generator is required for control, operating at the emitter resonance frequency. They have an operating frequency range from 500 to 6000 Hz, an operating voltage from 0 to 30 V, a peak sound intensity of 80 - 90 dB is in the frequency range from 3 to 5 kHz.

SMAT Series Sound Emitters

SMAT sounders are available in five sizes: 13mm, 17mm, 21mm, 24mm and 30mm, in output and surface mount versions.

Peculiarities:

• Octagonal shape;
• Models with various forms of conclusions;
• Lightweight monolithic construction;
• Ability to work in the frequency range;
• Ease of installation;
• The front panel is impact resistant and impervious to water and dust;
• No radiated electromagnetic fields.
