PUI Audio 85 dBA Through Hole Continuous Internal Magnetic Buzzer Component 9.5 mm 4 V dc Min 12 mm 12mm 7V dc Max

This magnetic buzzer component provides a Compact audible signalling solution for automation and electronics systems, producing a continuous tone for alarms and indicators while operating from a low-voltage supply. It is designed for through-hole PCB mounting and integrates an internal drive to simplify interfacing in control panels and equipment. Environmental considerations have been addressed through standard compliance suitable for industrial installations.

• 85dBA output delivers clearly audible alerts at close range
• 2000 to 2600Hz tone range ensures a recognisable continuous frequency
• Internal-drive arrangement simplifies wiring for quick integration
• Operates from 4 to 7V DC supply for flexible power arrangements
• Withstands temperatures up to 70°C for demanding environments

• Suitable for alarm circuits in machinery control panels
• Ideal for status indication in industrial automation racks
• Used for fault signalling in electrical distribution equipment
• Can be used for audible alerts on test rigs and bench instruments

It uses through-hole mounting, allowing soldered attachment directly to a PCB for secure mechanical and electrical connection.

The component is rated to operate at temperatures up to 70°C, maintaining tone stability within that range.

No external driver is necessary because it contains an internal drive circuit, so a simple DC supply within the specified voltage range is sufficient.

The unit functions correctly when supplied between 4V DC and 7V DC, operation outside this window may alter output or prevent normal function.
