BPC2316-2431 24V High Power Piezo Buzzer 23*16mm 3100Hz Built-in Circuit Piezo Buzzer for Alarm Systems

BPC2316-2431 23.3mm 24V Active Piezo Buzzer | 95dB Continuous Tone Internal Drive Piezoelectric Buzzer

The BPC2316-2431 piezoelectric buzzer is an active acoustic alarm component with integrated driving circuit. Unlike passive buzzers, it can emit stable continuous warning sound directly once connected to DC power within 5–28V, without extra drive circuits or signal modules. It features a resonant frequency of 3100±500Hz and impressive 95dB minimum sound output, delivering loud, clear alert signals for industrial and security devices. The shell adopts premium black PPO material, which brings excellent heat resistance and aging resistance. It supports -20℃ ~ +70℃ working temperature and adapts to tough indoor industrial environments. This 23.3*16mm through-hole pin buzzer is designed for direct soldering on PCB boards. Strict production testing guarantees consistent acoustic performance and long service life for mass manufacturing orders.

FAQ

Q1: Is this active or passive buzzer? A: It is an active piezo buzzer with internal driving circuit. It will sound directly when powered by 5–28V DC, no external square wave signal needed.

Q2: Can we customize it to intermittent beep sound? A: The standard version outputs continuous tone. Intermittent sound customization is available for bulk orders.

Q3: What is the test condition for 95dB? A: Sound level is tested at 10cm distance under rated 24VDC supply.

Q4: Why use PPO housing instead of normal plastic? A: PPO material has better heat resistance, low creep and anti-aging property, more suitable for long-running industrial alarm devices.

Q5: Can I get samples for testing? A: Yes, samples are available for performance verification. Please send an inquiry to confirm sample cost and shipping.
