Product Dimension & Structure

This large round piezo buzzer uses high-performance Black Noryl housing. The engineering drawing shows full outline dimensions and two pin layout. Its bigger piezo diaphragm can produce louder sound compared with small-size piezo buzzers. The two through-hole pins can be directly soldered to PCB. Polarity marking helps engineers avoid wrong wiring during assembly.

Applications

Our pin-type piezoelectric buzzers are widely used for audio reminder and warning signals:

Household electrical appliances
Industrial control panels
Security alarm systems
Portable medical reminder instruments
Handheld testing & measuring equipment
IoT electronic devices
Automatic equipment prompt modules

FAQ

Q1: Is BP3075-28 active or passive piezo buzzer? It is passive piezoelectric buzzer, requiring external square wave drive signal to generate sound.

Q2: What is the advantage of Noryl housing? Black Noryl features high temperature resistance, good dimensional stability and strong impact resistance, suitable for industrial and high-temperature working environment.

Q3: Can I get samples for sound testing? Yes, we support sample supply for your prototype verification.

Q4: Can we customize pin length for bulk orders? Custom pin length and other parameters are available when order quantity meets MOQ.

Q5: Is this buzzer RoHS compliant? Yes, it meets RoHS requirements for worldwide electronic product export.
