CPE-400AC

Alarms, Buzzers, And Sirens Overview

The CPE-400AC is a piezoelectric sound transducer designed for audible signaling applications. It features a single-tone operating mode with a resonant frequency of 3.6 kHz and an acoustic output of 89 dB at 12V measured at 30 cm. The device operates on a DC input voltage range of 3 to 16 V, drawing a supply current of 8 mA. It utilizes screw terminals for electrical connection and is housed in a rectangular package suitable for panel mounting. The unit supports a wide operating temperature range from -30°C to +85°C.

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific terminal configuration and mounting hole dimensions against the mechanical drawings prior to PCB or panel layout finalization. Confirm that the required acoustic output level meets the ambient noise conditions of the target installation environment. Ensure the driving circuit provides stable DC voltage within the specified 3V to 16V range to maintain consistent performance and prevent component damage.

Alarms, Buzzers, And Sirens Selection Notes

Select this model when a robust, high-decibel audible alert is required for panel-mounted applications. The screw terminal option simplifies wiring compared to surface-mount alternatives. Consider the 89 dB SPL rating for environments requiring clear auditory notification. Evaluate the physical dimensions to ensure compatibility with available panel space and mounting constraints.

Alarms, Buzzers, And Sirens Part Context

This component belongs to the CPE series of piezoelectric buzzers manufactured by Same Sky. It is engineered for general-purpose audio indication tasks where durability and clear sound projection are priorities. The series offers various form factors and mounting styles to accommodate different enclosure designs and integration requirements across consumer and industrial electronics.

Alarms, Buzzers, And Sirens Replacement Considerations

Direct substitutes may include other piezoelectric buzzers with similar 89 dB SPL ratings and screw terminal interfaces. Verify that replacement parts match the 3.6 kHz frequency and 3-16V operating voltage range. Check mechanical footprint compatibility if panel mounting holes are fixed.
