The DB-E298 Piezo Buzzer is a high-output self-driven audible signalling device designed for industrial equipment, alarm systems, security products, automation controls, and electronic warning applications. Operating from a nominal 12V DC supply with a wide 3V to 28V DC operating range, this buzzer produces a distinctive fast pulse tone at approximately 2900Hz, ensuring alarms and notifications are easily recognised even in noisy environments.
Delivering a powerful 90dB sound output at 30cm while drawing only 9mA, the DB-E298 combines high acoustic performance with low power consumption. Its built-in oscillator eliminates the need for an external drive circuit, making installation quick and straightforward.
The buzzer features flexible lead wire termination (UL1007 AWG#28) for easy wiring into control panels, machinery, security systems, and electronic equipment. Its durable ABS housing provides excellent mechanical strength and long-term reliability for both indoor commercial and industrial applications.
With a fast pulse rate of approximately 95 pulses per minute, the DB-E298 is ideal for warning systems where an intermittent audible signal is more effective at attracting attention than a continuous tone.
