CPE-750

Alarms, Buzzers, And Sirens Overview

The CPE-750 is a panel-mount piezoelectric transducer manufactured by Same Sky. It operates at a nominal voltage of 12 VDC with a supply current of 8 mA. The device produces a sound pressure level of 80 dB at 12 V measured from a distance of 30 cm. Its resonant frequency is 3.6 kHz, and it supports single-tone operation. The unit features top porting and accepts termination via screw terminals or quick connect tabs measuring 0.189 inches (4.80 mm). It functions within an operating temperature range of -30°C to 85°C.

Alarms, Buzzers, And Sirens Feature Summary

• Integrates internal driving circuitry for simplified system integration
• Utilizes piezoelectric technology for reliable acoustic output
• Features top-port design for directed sound projection

Alarms, Buzzers, And Sirens Applications

• Industrial control panels requiring audible status indicators
• Appliance signaling systems
• Electronic equipment alarm circuits

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific termination style required, as the component supports both screw terminals and quick connect tabs. Confirm that the 12 VDC nominal voltage aligns with the target system power supply. Ensure the mounting hole dimensions accommodate the 37.8 mm diameter housing. Check environmental ratings if deployment exceeds the standard -30°C to 85°C operational range.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a self-contained buzzer with integrated drive electronics is necessary. The 80 dB output at 30 cm provides adequate audibility for general industrial environments. Consider the physical depth of 23.5 mm during enclosure design. The 3.6 kHz frequency offers a distinct tone suitable for attention-grabbing alerts without excessive harshness.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the Same Sky line of active electronic components designed for audio indication. It serves as a direct replacement for generic 12 V piezo buzzers in legacy designs. The manufacturer transition from CUI Devices to Same Sky requires careful verification of datasheet revisions to ensure parameter consistency across updated documentation.

Alarms, Buzzers, And Sirens Replacement Considerations

Direct substitutes must match the 12 VDC rating, 80 dB SPL, and 3.6 kHz frequency. Verify mechanical compatibility regarding the 37.8 mm diameter and 23.5 mm depth. Ensure the replacement supports the same termination methods to avoid rewiring modifications.
