SM-D84552-2 Metal Buzzer 3VDC

From the shop's description

SM-D84552-2 Metal Buzzer 3VDC The Metal Buzzer 3 V DC is a compact electromechanical sound component, typically built with a metal housing that lends both durability and crisp acoustic resonance. It features two pin connectors for straightforward soldering or breadboard testing. Internally, an oscillator circuit drives a solenoid coil that vibrates a diaphragm to produce a consistent tone no external AC drive is required. The metal enclosure amplifies and directs the sound, providing a piercing beep at around 2.3 kHz. The construction ensures solid acoustic performance even under varying environmental conditions, while the sealed design helps to protect the internal components. With a typical operating current around 30 mA, the buzzer offers ample volume (approximately 80 dB at 10 cm). It’s engineered to maintain performance across varied temperatures, and the robust metal casing helps resist physical shocks. Overall, it balances loudness, reliability, and ease of installation in a small footprint. Features: Durable metal housing for enhanced acoustic output. Built-in oscillator works with direct 3 V DC power. Generates a steady tone around 2.3 kHz. Robust design for consistent performance in varied environments.
