CPT-4011-85PM

Alarms, Buzzers, And Sirens Overview

The CPT-4011-85PM is an externally driven piezoelectric audio transducer manufactured by Same Sky. It features a round design with a diameter of 46.5 mm and a height of 12 mm. The device operates at a resonant frequency of 3.25 kHz and produces a sound pressure level of 85 dB when driven at 50 V. It has a voltage rating of 12 Vp-p and draws a current of 30 mA. The unit utilizes wire leads for connection and includes a flange for panel mounting.

Alarms, Buzzers, And Sirens Feature Summary

• Externally driven piezoelectric technology for active sound generation
• Integrated flange structure designed for secure panel mounting applications
• Wire lead termination method for direct circuit integration

Alarms, Buzzers, And Sirens Applications

• Industrial equipment status indicators
• Appliance audible alerts
• Control panel alarm systems

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm electrical ratings and mechanical dimensions. Ensure the driving circuit matches the 12 Vp-p requirement and 30 mA current draw. Confirm panel cutout specifications align with the 46.5 mm diameter and flange design before procurement.

Alarms, Buzzers, And Sirens Selection Notes

Select this component for applications requiring high-volume acoustic output in a compact form factor. The externally driven nature allows for flexible frequency control beyond the resonant peak. Consider the through-hole wire lead configuration for robust connections in industrial environments where surface mount options are unsuitable.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the CPT series of piezoelectric buzzers from Same Sky, formerly CUI Devices. The series offers various sizes and drive configurations. This specific model emphasizes panel mounting convenience via its flange design, distinguishing it from board-mount or PCB-integrated alternatives within the broader product portfolio.

Alarms, Buzzers, And Sirens Replacement Considerations

Cross-reference with other CPT-4011 variants for dimensional compatibility. Verify that substitute parts match the 3.25 kHz frequency and 85 dB SPL requirements. Check if alternative models offer different voltage ratings while maintaining the same physical footprint and mounting style.
