SCE048XA3DP2B

Alarms, Buzzers, And Sirens Overview

The SCE048XA3DP2B is an internally driven piezoelectric audio indicator manufactured by Mallory Sonalert Products Inc. It operates within a voltage range of 28 V to 48 V and draws a current of 40 mA. The device produces a sound pressure level of 95 dB at 28 V measured at 61 cm, with a frequency of 2.9 kHz. It features a slow double pulse operating mode and utilizes terminal block connections for installation.

Alarms, Buzzers, And Sirens Feature Summary

• Internally driven piezoelectric technology for direct connection applications
• Slow double pulse acoustic output pattern
• Terminal block termination style for secure wiring

Alarms, Buzzers, And Sirens Applications

• Industrial machinery status indication
• Control panel alarm signaling
• Equipment fault detection systems

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific acoustic waveform requirements against the slow double pulse specification before procurement. Confirm that the terminal block interface matches the existing wiring harness or PCB layout constraints. Ensure the operating voltage range aligns with the system power supply to prevent damage or insufficient actuation.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a reliable, internally driven audible alert is required for industrial environments. The 2.9 kHz frequency provides distinct audibility, while the 95 dB output ensures presence in noisy settings. Verify compatibility with the 28-48 V DC supply network and ensure sufficient panel space for the mounting dimensions.

Alarms, Buzzers, And Sirens Part Context

This unit belongs to the SCE series of audio indicators from Mallory Sonalert. The series is characterized by piezoelectric construction and internal drive circuits, simplifying integration into control systems. The SCE048XA3DP2B specifically targets applications requiring robust, panel-mounted audible alerts with standardized electrical interfaces.

Alarms, Buzzers, And Sirens Replacement Considerations

Cross-reference with other SCE series models such as SCE048XD2DP3B for similar form factors but different acoustic outputs. Verify that any substitute maintains the same voltage range, current draw, and terminal block configuration to ensure mechanical and electrical compatibility.
