SCE028XA2DP2B

Alarms, Buzzers, And Sirens Overview

The SCE028XA2DP2B is an internally driven piezoelectric buzzer from the SCE series by Mallory Sonalert Products Inc. It operates on a DC input voltage range of 16 to 28V with a current consumption of 40mA. The device produces a fast double pulse tone at a frequency of 3kHz, achieving a sound pressure level of 105dB at 61cm. It features terminal block connections and panel mount installation. The unit has a diameter of 42.85mm and a maximum height of 50.80mm, operating within a temperature range of -40°C to 85°C.

Alarms, Buzzers, And Sirens Feature Summary

• Internally driven piezoelectric technology for simplified circuit integration
• Fast double pulse operation mode for distinct audible alerts
• High sound pressure output suitable for noisy industrial environments
• Terminal block termination for secure electrical connections

Alarms, Buzzers, And Sirens Applications

• Industrial machinery status indication
• Factory automation equipment alarms
• Control panel warning systems
• Heavy-duty appliance safety alerts

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific part number suffix against official Mallory Sonalert documentation to ensure correct acoustic output and mounting configuration. Confirm that the required voltage range aligns with the system power supply. Check for RoHS compliance requirements if applicable to the target market. Ensure panel cutout dimensions match the specified diameter for proper fitment during installation.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a high-decibel alert is required in confined spaces. The internal driver eliminates the need for external oscillators. Compare with constant tone variants if continuous signaling is preferred over pulsed patterns. Verify that the 40mA current draw is supported by the control interface without additional buffering.

Alarms, Buzzers, And Sirens Part Context

This model belongs to the SCE series of industrial-grade audio indicators. It shares the same physical footprint and mounting style as other SCE028 variants but differs in acoustic characteristics such as frequency and waveform. The series is designed for harsh environments requiring reliable performance across wide temperature ranges.

Alarms, Buzzers, And Sirens Replacement Considerations

SCE028XD2DP2B offers similar dimensions and mounting but provides a 2kHz frequency instead of 3kHz. SCE028LD2DP2B is another alternative within the same series with comparable loudness levels. Verify exact acoustic specifications before substitution to ensure compatibility with existing alarm protocols.
