CPT-2521C-500

Alarms, Buzzers, And Sirens Overview

The CPT-2521C-500 is an externally driven piezoelectric audio transducer buzzer manufactured by Same Sky. It features a round design with a diameter of 25.6 mm and a height of 21 mm. The component operates at a rated voltage of 20 Vp-p and draws a current of 40 mA. It produces a sound pressure level of 95 dB at 20 V and resonates at a frequency of 3.7 kHz. The unit utilizes wire lead termination for through-hole mounting and carries an IP68 rating for waterproof protection.

Alarms, Buzzers, And Sirens Feature Summary

• IP68 rated waterproof housing suitable for harsh environments
• Externally driven piezoelectric transducer technology
• High acoustic output of 95 dB at rated voltage
• Through-hole wire lead termination for secure PCB attachment

Alarms, Buzzers, And Sirens Applications

• Industrial equipment requiring audible alerts
• Medical devices needing reliable audio indicators
• Consumer electronics with water exposure risks
• Automotive systems demanding robust signaling

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix and packaging configuration against the manufacturer's latest datasheet before ordering. Confirm that the external drive circuitry matches the 20 Vp-p requirement to ensure optimal performance. Check for any recent regulatory updates regarding RoHS compliance or material restrictions applicable to your region.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when high volume and environmental sealing are critical. The IP68 rating distinguishes it from standard buzzers, making it ideal for outdoor or washdown applications. Ensure the driving circuit can supply the necessary 40 mA current without exceeding the 20 Vp-p limit to prevent damage.

Alarms, Buzzers, And Sirens Part Context

This part belongs to Same Sky's line of piezoelectric audio transducers. It is designed as a direct replacement for similar waterproof buzzers in industrial and medical sectors. The product maintains compatibility with standard through-hole mounting techniques while offering enhanced durability compared to non-rated alternatives.

Alarms, Buzzers, And Sirens Replacement Considerations

Direct substitutes must match the 25.6 mm diameter, 3.7 kHz frequency, and IP68 rating. Verify that alternative parts support the same 20 Vp-p operating voltage and 40 mA current draw. Ensure the replacement also uses wire leads for compatible assembly processes.
