Overview

The CPT-1495C-300 is a 14mm round piezoelectric transducer designed for reliable acoustic feedback in space-constrained industrial designs. It operates at a resonant frequency of 4.25kHz and supports a wide input voltage range up to 30V. This buzzer utilizes wire lead connections for flexible mounting away from the primary PCB.

Why Choose This Part

The wide 0V to 30V operating range allows for use in both low-power 3.3V logic systems and standard 24V industrial rails. Its piezoelectric design ensures minimal current draw compared to electromagnetic alternatives while maintaining a compact 14mm profile.

Applications

Industrial Control Panels
Provides audible alerts for operator input confirmation or system status changes in high-voltage environments.
Handheld Instrumentation
Integrates into portable devices where a small 14mm footprint is required for battery-efficient sound generation.
Safety Alarms
Used as a primary or redundant signaling device in alarm systems requiring high-frequency tonal output.

Getting Started

To drive this transducer, provide a square wave at its resonant frequency of 4.25kHz using a microcontroller PWM output and a simple NPN transistor or MOSFET switching circuit. Ensure the peak-to-peak voltage does not exceed the 30V rating and use the wire leads for secure chassis or panel mounting.
