PUI Audio Piezo Buzzer Transducer, 95dBA Sound Level, 2 to 5V Supply Voltage - SMTB-0927-TW-R


This piezo buzzer transducer is a Compact audible signalling device designed for surface-mount integration on electronic assemblies. It produces a high sound pressure level suitable for alerting and alarm functions and operates with an externally driven input across a low-voltage range, making it appropriate for control panels and embedded systems in industrial environments.

Features and Benefits:


• 95 dBA output for clear audible alerts at distance
• External drive allows custom tone and volume control
• Operates from 2V to 5V to suit common logic levels
• Frequency band 2500 to 2900 Hz for effective human hearing response
• Surface-mount construction for automated PCB assembly
• Rated to 105 °C for use in elevated temperature assemblies

Applications


• Suitable for industrial automation alarm panels
• Ideal for safety warning circuits in machinery
• Used with control units requiring Compact audible alerts
• Can be used for status indication in embedded systems
• Suitable for environmental monitoring alarms on PCBs

What mounting method does it require on a board?


It is intended for surface-mount placement and soldering to PCB pads during reflow assembly.

How does temperature affect installation choices?


The device withstands up to 105 °C, so standard soldering profiles for SMT components and nearby high-temperature parts are acceptable.

What acoustic range should designers expect for alert audibility?


The transducer emits sound predominantly between 2500 Hz and 2900 Hz, a band that penetrates ambient noise in typical industrial environments.

Which supply voltages will reliably drive the unit?


The device accepts drive voltages from 2V up to 5 V, designers should ensure external drive circuitry provides appropriate drive amplitude and waveform.
