SCE048LD3DP2B

Alarms, Buzzers, And Sirens Overview

The SCE048LD3DP2B is a piezoelectric audio indicator manufactured by Mallory Sonalert Products Inc. It operates within a voltage rating of 28 VAC to 48 VAC and draws a current of 40 mA. The device produces a loud sound level at a frequency of 2 kHz using a fast double pulse mode. It features panel mounting with a knurled nut and is designed for industrial environments, supporting NEMA 3R, 4X, and 12 enclosures.

Alarms, Buzzers, And Sirens Feature Summary

• Piezoelectric technology for reliable acoustic signaling
• Fast double pulse operation mode for distinct alerts
• Panel mount construction with knurled nut for secure installation
• Compliance with cUL recognition standards

Alarms, Buzzers, And Sirens Applications

• Industrial control panels requiring audible alarms
• Automation equipment status indicators
• Electrical enclosures needing NEMA-rated audio alerts

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific ordering suffix against the manufacturer's Sales Outline Drawing to ensure correct voltage and mode configuration. Confirm that the required enclosure ratings match the component's cUL and NEMA specifications. Check for RoHS compliance details if environmental regulations apply to the deployment site.

Alarms, Buzzers, And Sirens Selection Notes

Select this model when a loud, high-frequency alert is required for 28-48 VAC systems. The fast double pulse mode distinguishes it from continuous tone indicators. Ensure the mounting hole diameter accommodates the specified housing dimensions and that the operating temperature range meets the application's thermal requirements.

Alarms, Buzzers, And Sirens Part Context

This component belongs to the SCE series of audio indicators and alerts. The series offers various voltage ratings, frequencies, and sound modes to suit different industrial signaling needs. The SCE048LD3DP2B specifically addresses applications requiring loud, pulsed alerts in standard industrial voltage ranges.

Alarms, Buzzers, And Sirens Replacement Considerations

Consult the official Mallory Sonalert cross-reference guide for verified substitutes. Ensure any replacement matches the 28-48 VAC input, 40 mA current draw, and 2 kHz frequency. Verify physical mounting compatibility and acoustic output levels before substitution.
