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) #CommonPartsLibrary #Audio-Product #Alarm #Buzzer #Siren
