Piezo Buzzer Transducers

Same Sky Piezo Buzzer Transducers are externally driven indicators that are available in panel-mount, surface-mount, through-hole mount, or wire leads mounting styles. These devices operate at frequencies up to 4.1MHz. Same Sky piezo transducers offer a 65dB to 115dB sound pressure level (SPL) range and an operating temperature range from -40°C to +120°C. The buzzer transducers are ideal for a variety of consumer electronics, industrial, and portable equipment applications.
