SMA-30-P15, 30mm, Piezoelectric Emitter with generator
see technical documentation
Sonitron's multifunctional transducers and transducers have been specifically designed to meet the various customer requirements for size, mounting, terminations and sound pressure. The emitters of these series produce a clean, clear sound and are very reliable. All models are available in surface and output mount versions with sizes: 13 mm, 17 mm, 21 mm, 24 mm, 30 mm.
Sound emitters of the SMA series have a low cost with high consumer characteristics. The series contains a wide range of devices with different power consumption, operating voltage, sound pressure. These emitters have a built-in oscillator that produces a very clear tone signal.
Applications: automatic doors, alarms, metal detectors, gas detectors, measuring and medical equipment, timers, control systems, cars and trucks, toys, computer peripherals.
