CPI-3020-90T

Alarms, Buzzers, And Sirens Overview

The CPI-3020-90T is an internally driven piezoelectric buzzer manufactured by Same Sky. It operates on a DC voltage range of 3 to 24 VDC with a nominal rating of 12 VDC. The device draws 12 mA of current and produces a sound pressure level of 93 dB at 12 VDC. Its acoustic frequency is 3.5 kHz, emitting a continuous tone. The unit features 30 cm wire leads for connection and utilizes through-hole PC pins for mounting.

Alarms, Buzzers, And Sirens Feature Summary

• Internally driven piezoelectric design eliminates the need for external oscillators
• Wide operating voltage range supports 3 to 24 VDC applications
• Fixed continuous tone output at 3.5 kHz frequency
• Integrated 30 cm wire leads facilitate direct wiring connections

Alarms, Buzzers, And Sirens Applications

• Industrial control panel status indicators
• Appliance audible alerts
• Medical equipment signaling
• HVAC system notifications

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix '90T' corresponds to the required lead length and pin configuration. Confirm that the 3-24 VDC input range aligns with the target circuit supply. Ensure mechanical clearance accommodates the internal piezo element dimensions. Cross-reference the datasheet for acoustic testing conditions to validate performance expectations in the final assembly environment.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a self-contained audio source is required without complex driver circuits. The wide voltage tolerance simplifies power supply design across various industrial standards. Consider the fixed 3.5 kHz tone if variable pitch signaling is not necessary. Evaluate the 93 dB output against ambient noise levels to ensure adequate audibility for the intended installation location.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the Same Sky piezoelectric buzzer family, formerly associated with CUI Devices. It serves as a direct replacement for legacy CUI models within the CPI series. The component integrates the drive electronics directly onto the transducer, offering a compact solution for simple alerting tasks in embedded systems and standalone devices.

Alarms, Buzzers, And Sirens Replacement Considerations

Check for exact pinout compatibility when substituting older CUI devices. Verify that the acoustic output meets regulatory requirements for the specific application zone. Ensure the operating voltage does not exceed the maximum rating during transient events.
