PUI Audio 95 dBA Lead Wire Continuous Buzzer 3 V dc Min 15V dc Max

This buzzer is a Compact acoustic warning device designed for industrial and outdoor signalling in automation and electrical systems. It produces a continuous audible alert within a defined frequency band and operates across a broad supply range, making it suitable for diverse control panels and alerting circuits where a clear, sustained alarm tone is required.

• Emits 104dB sound pressure for high audibility in noisy environments
• Operates from 3V to 15V providing flexible supply compatibility
• Frequency range 2500 to 3500Hz optimised for attention-grabbing tones
• Draws 25mA to minimise power consumption in battery-backed systems
• Continuous tone via lead wire termination for simple wiring integration
• RoHS-compliant construction for adherence to restricted substances

• Suitable for factory automation alarm panels requiring loud alerts
• Ideal for access control systems demanding continuous tone signalling
• Used with outdoor enclosures where waterproof acoustic output is needed
• Can be used for machinery guard warning in mechanical workshops
• Used for safety annunciation in electrical distribution cabinets

The device functions between -20°C and 70°C, so it should be sited where ambient conditions remain within that span.

It uses lead wires for termination, allowing direct connection to control boards or harnesses without PCB soldering.

When powered within its voltage range it produces a continuous single-frequency alarm suitable for persistent warning indications.

Its overall form factor includes a low-profile height of 4.2mm, enabling placement in shallow enclosures or slim panels.
