SCE048SA3DL1B

Alarms, Buzzers, And Sirens Overview

The SCE048SA3DL1B is an internally driven piezoelectric buzzer from the SCE series by Mallory Sonalert. It operates on a DC input voltage range of 28 to 48V with a current draw of 40mA. The device generates a sound pressure level of 65dB at 28V measured at a distance of 61cm. Its acoustic frequency is 2.9kHz, and it features a 10-second on-delay timing mode. The unit utilizes panel mount installation via terminal block connections.

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix DL1B against official Mallory Sonalert documentation to confirm the 10-second delay function and 65dB SPL rating. Ensure the operating environment supports the specified 28-48V DC input range. Confirm that terminal block termination meets the mechanical requirements of the target enclosure design before finalizing procurement.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a delayed activation signal is required for safety or sequencing purposes. The internal driver simplifies circuit design by eliminating external oscillators. Verify that the 65dB output level is sufficient for the ambient noise conditions of the intended application site.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the SCE series of industrial-grade audio indicators. The series offers various timing modes and acoustic outputs tailored for harsh environments. Mallory Sonalert designs these units to meet rigorous industrial standards for reliability and consistent performance over extended operational lifespans.

Alarms, Buzzers, And Sirens Replacement Considerations

Cross-reference with other SCE series variants such as SCE048SA3SS1B for different timing profiles. Ensure any substitute maintains the same 28-48V DC input requirement and terminal block mounting style to fit existing hardware without modification.
