SCE120SA3SU2B

Alarms, Buzzers, And Sirens Overview

The SCE120SA3SU2B is an industrial-grade piezoelectric buzzer from the SCE series, designed for audible alerts. It operates on a voltage range of 30 to 120 VAC with a rated voltage of 120 VAC and a current rating of 40 mA. The device emits a soft tone at a frequency of 3 kHz using a fast speed-up modulation pattern. It features panel mount installation with terminal block connections.

Alarms, Buzzers, And Sirens Feature Summary

• Fast speed-up acoustic modulation for distinct alert signaling
• Soft tone profile suitable for specific environmental noise requirements
• Integrated internal driver circuitry for direct AC connection
• Terminal block termination for secure wiring

Alarms, Buzzers, And Sirens Applications

• Industrial machinery status indicators
• Electrical panel alarm systems
• Medical equipment failure alerts
• HVAC system fault notifications

Alarms, Buzzers, And Sirens Procurement Notes

Verify that the application supply voltage remains within the specified 30-120 VAC range to ensure proper operation. Confirm that transient voltage surge suppression is employed in the circuit design as required by the component specifications. Ensure the mounting environment supports the panel mount form factor and terminal block connectivity.

Alarms, Buzzers, And Sirens Selection Notes

Select this model when a soft acoustic profile with rapid onset is required for high-voltage AC applications. Compare against other SCE variants if different modulation patterns or sound pressure levels are needed. Verify that the 40 mA current draw aligns with the available power supply capacity in the target control circuit.

Alarms, Buzzers, And Sirens Part Context

This component belongs to the SCE series of audio indicators manufactured by Mallory Sonalert Products Inc. The series provides various acoustic options including constant tones, dual tones, and modulated alerts. These devices are engineered for reliability in industrial environments and typically feature robust construction suitable for panel mounting.

Alarms, Buzzers, And Sirens Replacement Considerations

SCE120SA3SS1B offers similar electrical characteristics but utilizes a different modulation pattern (1 min on/constant). SCE120XA3SU1B provides a louder xloud output with comparable voltage ratings. Evaluate acoustic requirements before substituting.
