Piezo Buzzer [PS1240]

Piezo Buzzer [PS1240]

We have ✅ 10 available of the AF-160 in our Sydney warehouse. An extra 100 units available with a short lead time.

Express post delivery (2-5 business days)

The PS1240 is a compact piezo buzzer for generating beeps, tones, and alerts in electronic projects. Drive it with a 3–30 V peak-to-peak square wave from a timer or microcontroller. It produces its loudest output around 4 kHz but works well across the 2–10 kHz range.

For extra volume, use differential drive by connecting both pins to microcontroller outputs and alternating which pin is high — this doubles the effective drive voltage.

Key Features

  • Wide Voltage Range – 3–30 V peak-to-peak square wave input
  • Loudest at 4 kHz – Effective across 2–10 kHz frequency range
  • Simple Wiring – Connect one pin to ground, the other to a square wave output
  • Differential Drive Option – Double volume by driving both pins from a microcontroller
  • Compact Size – Small form factor for embedded projects

Package Contents

  • 1× PS1240 Piezo Buzzer
