SCE048MA3DP3S

Alarms, Buzzers, And Sirens Overview

The SCE048MA3DP3S is a piezoelectric audio indicator manufactured by Mallory Sonalert Products Inc. It operates on a DC voltage range of 28 to 48V with a current draw of 40 mA. The device produces a sound level of 75 dB at 28V measured from a distance of 61 cm. It features an internal driving circuit and emits a double pulse tone at a frequency of 2.9 kHz. The unit utilizes panel mount installation with terminal block connections.

Alarms, Buzzers, And Sirens Feature Summary

• Integrates an internal driving circuit for direct connection without external drivers
• Produces a distinct double pulse acoustic signal for alert identification
• Constructed with piezoelectric technology for reliable operation
• Designed for secure panel mounting applications

Alarms, Buzzers, And Sirens Applications

• Industrial machinery status indication
• Control panel alarm signaling
• Automotive equipment monitoring
• Medical device auditory alerts

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix DP3S against official Mallory Sonalert documentation to confirm the exact acoustic pattern and termination style. Ensure the input power supply matches the 28-48V DC requirement. Confirm that the 75 dB sound pressure level meets the environmental noise requirements of the intended installation site before finalizing procurement.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a built-in driver is required to simplify circuit design. The 2.9 kHz double pulse frequency offers high distinguishability in noisy environments. Verify that the panel cutout dimensions accommodate the 42.85 mm diameter housing. Ensure the operating temperature range of -40°C to 85°C aligns with the system's thermal conditions.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the SCE series of audio indicators, which are characterized by their compact size and robust construction. The series includes various models with different voltages, frequencies, and acoustic patterns. The SCE designation typically indicates a standard industrial-grade buzzer suitable for harsh environments requiring cUL recognition.

Alarms, Buzzers, And Sirens Replacement Considerations

Direct replacements must match the 28-48V DC input, 40 mA current draw, and 42.85 mm diameter. Verify that substitute parts offer equivalent 75 dB SPL and compatible terminal block mounting. Cross-reference the double pulse pattern with alternative model numbers if acoustic signature consistency is critical.
