DB-A240 240VAC Panel Mount Piezo Buzzer 80dB Pulse Tone 43.5mm

The DB-A240 Piezo Panel Mount Buzzer is a robust audible signalling device designed for industrial control panels, electrical equipment, machinery, automation systems, and commercial installations. Operating directly from a 240V AC power supply, this self-driven piezo buzzer produces a distinctive pulse tone, providing highly effective audible warnings for alarms, equipment faults, process notifications, and operator alerts.

Producing a clear 80dB sound output at 30cm, the DB-A240 delivers reliable acoustic performance while consuming only 10mA, making it an energy-efficient solution for continuous industrial operation. The pulse tone is particularly effective for attracting attention in noisy environments, helping operators quickly recognise alarm conditions.

The buzzer features a durable 43.5mm round panel-mount housing with a 49.5mm depth, allowing secure installation into control cabinets, switchboards, machine panels, and electrical enclosures. Its rugged construction ensures dependable long-term performance in demanding industrial and commercial environments.

Using reliable piezoelectric technology, the DB-A240 offers long service life, low power consumption, and maintenance-free operation. It is suitable for OEM equipment, factory automation, HVAC systems, power distribution panels, security systems, and general industrial warning applications.
