SCE048MD3SS1B

Alarms, Buzzers, And Sirens Overview

The SCE048MD3SS1B is an industrial-grade piezoelectric buzzer from the SCE series by Mallory Sonalert. It operates on a DC voltage range of 28 to 48V with a rated current of 40 mA. The device emits a medium volume sound at a frequency of 3 kHz. Its operational mode is defined as one minute of continuous tone followed by a constant off period. This component is designed for panel mounting applications requiring reliable audio indication in industrial environments.

Alarms, Buzzers, And Sirens Feature Summary

• Features an internal driver circuit for direct connection to power sources without external oscillators.
• Provides a distinct medium-volume acoustic signal suitable for industrial alerting needs.
• Constructed with piezoelectric technology for durable and consistent performance.
• Includes UL and cUL certification for compliance in regulated industrial settings.

Alarms, Buzzers, And Sirens Applications

• Industrial machinery status indicators
• Control panel alarm systems
• Equipment fault detection alerts

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific ordering suffix to ensure the correct voltage, frequency, and acoustic output match the design requirements. Confirm that the 28-48VDC input specification aligns with the system power supply. Check for RoHS compliance documentation if environmental regulations apply to the deployment location. Ensure the panel mounting dimensions are compatible with the enclosure design before finalizing procurement.

Alarms, Buzzers, And Sirens Selection Notes

Select this model when a medium-intensity audible alert is required within a 28-48VDC operating window. The 3kHz frequency offers good penetration in noisy environments. Consider the one-minute on/constant off cycle for applications where prolonged continuous sounding is not necessary or permitted. Compare against soft or loud variants if different acoustic profiles are needed for the same voltage range.

Alarms, Buzzers, And Sirens Part Context

This component belongs to the SCE series of audio indicators, which are widely used in industrial control panels. The series offers various voltage ratings and acoustic outputs to suit different equipment requirements. Mallory Sonalert designs these devices for robustness in harsh conditions, ensuring long-term reliability for critical signaling tasks in manufacturing and automation sectors.

Alarms, Buzzers, And Sirens Replacement Considerations

Check for other SCE series parts with identical 28-48VDC ratings and 3kHz frequency but different acoustic levels (soft or loud) if volume adjustment is needed. Verify physical dimensions and terminal types to ensure mechanical compatibility during replacement.
