CPI-4116-89PM

Alarms, Buzzers, And Sirens Overview

The CPI-4116-89PM is a piezoelectric audio indicator buzzer manufactured by Same Sky. It operates at a rated voltage of 12 VDC with a current consumption of 10 mA. The device produces a single-tone sound pressure level of 89 dB at a frequency of 3.6 kHz. Mechanically, it features a circular body with a diameter of 41.8 mm and a maximum seated height of 16.5 mm. Termination is achieved via wire leads, and the unit is designed for panel mounting applications.

Alarms, Buzzers, And Sirens Feature Summary

• Integrates an internal driving circuit for simplified interface requirements
• Utilizes piezoelectric technology for reliable acoustic signal generation
• Designed for direct panel mounting with flange-style installation

Alarms, Buzzers, And Sirens Applications

• Industrial control panels requiring audible status alerts
• Medical equipment safety signaling systems
• Automotive instrumentation dashboards

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific acoustic output and operating voltage against the official Same Sky datasheet before integration. Confirm that the wire lead termination style matches the system wiring harness. Ensure the panel cutout dimensions accommodate the 41.8 mm diameter and 16.5 mm height constraints to guarantee proper mechanical fit and sealing.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a high-decibel, single-frequency alert is required for 12 VDC systems. The integrated driver eliminates the need for external oscillators. Compare the 89 dB output against ambient noise levels in the target environment. Consider the wire lead configuration for routing flexibility compared to surface-mount alternatives.

Alarms, Buzzers, And Sirens Part Context

This model belongs to the CPI-4116 series of industrial-grade piezo buzzers from Same Sky. The series offers various decibel ratings and voltage options within a standardized 41.8 mm form factor. This specific variant provides a balance between moderate sound pressure and low power consumption suitable for battery-backed or low-power industrial interfaces.

Alarms, Buzzers, And Sirens Replacement Considerations

Direct substitutes include CPI-4116-85PM (85 dB) and CPI-4116-96PM (96 dB). These share identical mechanical dimensions and electrical interfaces but differ in acoustic output. Verify that the alternative decibel rating meets the specific audibility requirements of the application.
