9 mm, 3 V, 85 dB, Through Hole, Magnetic Audio Buzzers Transducer, Externally Driven Magnetic 3 V 80mA 2.73kHz 85dB @ 3V, 10cm Through Hole PC Pins #Alarm #Buzzer #Siren #Audio
The KPEG112 is a piezoelectric sounder / passive piezo transducer commonly used for audible signaling such as beeps, alarms, and electronic alerts.
It works by converting an electrical AC signal into mechanical vibration through a piezoelectric ceramic element, producing sound.
Type: Passive piezoelectric transducer (not an active buzzer)
Operation: Requires an external driving signal (PWM or oscillator)
Construction: Piezo ceramic disk inside a plastic housing
Sound Output: Tone depends on input frequency (typically in the kHz range)
Terminals: 2-pin connection (generally non-polarized)
