SCE048LA2CT1B

Alarms, Buzzers, And Sirens Overview

The SCE048LA2CT1B is an internally driven piezoelectric buzzer from the Sonalert series by Mallory Sonalert Products Inc. Designed for panel mounting, this component operates on AC or DC input within a voltage range of 28 to 48V. It draws a supply current of 40mA and produces a continuous tone at a frequency of 2kHz. The acoustic output is rated at 85dB measured at 28V and 61cm. The unit features terminal block connections and has a diameter of approximately 42.85mm.

Alarms, Buzzers, And Sirens Feature Summary

• Internally driven piezoelectric technology for simplified circuit integration
• Continuous tone operation suitable for steady-state alarm signaling
• Panel mount construction with terminal block termination
• Compatible with both AC and DC power supplies

Alarms, Buzzers, And Sirens Applications

• Industrial control panels requiring audible status indicators
• Equipment failure alarm systems
• Medical device alerting mechanisms
• General purpose safety warning units

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix CT1B against official Mallory documentation to confirm terminal type and acoustic characteristics. Ensure input voltage matches the 28-48V range. Confirm panel cutout dimensions align with the 42.85mm diameter specification before procurement.

Alarms, Buzzers, And Sirens Selection Notes

Select this model when a continuous audible signal is required rather than pulsed tones. It is appropriate for applications needing internal drive capability to reduce external component count. Consider the 85dB SPL rating for environmental noise levels. Verify compatibility with available mounting space and wiring methods using terminal blocks.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the Sonalert SCE series, which focuses on industrial-grade audio indicators. The series typically offers various sound patterns and voltages. The SCE048LA2CT1B specifically provides a standard continuous tone option for general alarm duties within the higher voltage operating range of the family.

Alarms, Buzzers, And Sirens Replacement Considerations

Direct substitutes may include other SCE series parts with matching voltage and terminal configurations. Verify that replacement units maintain the same 2kHz frequency and 85dB output level. Check physical dimensions to ensure fit in existing panel cutouts.
