The Small Buzzer 3V-24V is a compact piezoelectric alarm buzzer that produces a loud, continuous tone across a wide 3V to 24V supply range, making it easy to drive from almost any microcontroller, relay, or alarm circuit. Its flange mount and pre-attached wire leads make it simple to fix inside enclosures for alarms and notification circuits.
Key features:
- Wide Voltage Range: Sounds continuously anywhere from 3V to 24V DC, so no separate regulator is needed for most projects.
- Loud Output: Produces a clearly audible continuous tone suitable for alarms, timers, and equipment notifications.
- Two-Wire Leads: Ships with red and black wire leads already attached, ready to connect without extra soldering.
- Flange Mounting: Two mounting holes in the base let it be screwed securely into a panel or enclosure.
- Compact Size: Small footprint fits easily inside project boxes, alarm panels, and control cabinets.
- Durable Housing: Sealed plastic case protects the internal element from dust and light moisture.
Because it is an active buzzer, it only needs a steady DC voltage across its two leads to sound continuously, with no oscillator circuit required.
