SCE028SA3DP2B

Alarms, Buzzers, And Sirens Overview

The SCE028SA3DP2B is an industrial-grade piezoelectric buzzer from the Mallory Sonalert SCE series. It operates on a voltage range of 16 to 28 VAC or VDC with a rated current of 40 mA. The device features an internal driver circuit and produces a fast double pulse tone at a frequency of 3 kHz. It offers medium sound pressure levels and utilizes terminal block connections for panel mounting applications.

Alarms, Buzzers, And Sirens Feature Summary

• Internal driver circuit enables direct connection to power sources without external oscillators
• Piezoelectric technology ensures reliable operation in industrial environments
• Terminal block termination facilitates secure electrical connections

Alarms, Buzzers, And Sirens Applications

• Industrial machinery status indicators
• Factory equipment alarm systems
• Control panel audio alerts

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix DP2B against official Mallory Sonalert documentation to confirm the fast double pulse waveform and medium acoustic output specifications. Ensure the operating environment supports the 16-28V AC/DC input range and that panel mounting provisions accommodate the unit's physical dimensions. Confirm compliance requirements such as RoHS status through manufacturer datasheets prior to procurement.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a self-contained audible indicator with a distinct double-pulse warning pattern is required. The SCE series provides robust construction suitable for harsh conditions. Consider the 40 mA current draw and terminal block interface during system design. Verify that the medium sound level meets the ambient noise requirements of the installation site.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the SCE series of electronic volume control compatible alarms, although this specific model lacks the VC suffix. The series is designed for industrial applications requiring durable audio signaling. Mallory Sonalert manufactures these devices to meet stringent reliability standards for continuous operation in critical infrastructure and manufacturing settings.

Alarms, Buzzers, And Sirens Replacement Considerations

Consult official Mallory Sonalert substitution guides for verified equivalents. Cross-referencing requires matching the 3 kHz frequency, double pulse mode, and 16-28V operational range. Generic buzzers may not replicate the specific acoustic profile or internal driver characteristics.
