# KPEG112 (Component) ## Description 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 ## Component Details - **Owner:** adrian95 - **Created:** 4/17/2026 - **Last Updated:** 4/17/2026 - **Visibility:** Public - **Manufacturer Part Number:** KPEG112 - **License:** https://creativecommons.org/licenses/by/4.0/ - **Manufacturer Name:** KINGSTATE - **Part Type:** Buzzer - **Datasheet URL:** https://www.farnell.com/datasheets/4320648.pdf - **Part Type:** Electromechanical Components - **MPN:** KPEG112 - **Pin Count:** 2 ## Pins | Pin | Name | Type | |-----|------|------| | 1 | - | | | 2 | + | | --- *Generated from [https://www.flux.ai/adrian95/kpeg112](https://www.flux.ai/adrian95/kpeg112)*
