SCE120SD6CT1S

Alarms, Buzzers, And Sirens Overview

The SCE120SD6CT1S is an internally driven piezo buzzer from the Mallory Sonalert SCE series, designed for panel mounting. It operates on a voltage range of 48 to 120 VDC with a rated current of 40 mA. The device produces a continuous tone at a frequency of 1.9 kHz and delivers a sound pressure level of 65 dB when measured at 48 V and 61 cm. It utilizes screw terminal or quick connect tab connections for secure installation.

Alarms, Buzzers, And Sirens Feature Summary

• Internally driven piezoelectric technology eliminates the need for external oscillators
• Designed for direct connection to high-voltage DC control circuits
• Panel mount construction with screw terminal or quick connect tab interfaces

Alarms, Buzzers, And Sirens Applications

• Industrial machinery status indicators
• Control panel alarm systems
• High-voltage DC equipment monitoring

Alarms, Buzzers, And Sirens Procurement Notes

Verify that the supply voltage strictly adheres to the 48-120 VDC specification. Ensure transient voltage surge suppression is employed in the circuit design as recommended by the manufacturer. Confirm the required connection type matches the available terminal options.

Alarms, Buzzers, And Sirens Selection Notes

Select this component for applications requiring a self-contained audible alert powered directly by high-voltage DC sources. The internal drive circuit simplifies board layout by removing external driver requirements. Verify physical dimensions and terminal compatibility against existing panel cutouts and wiring harnesses.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the SCE industrial-grade buzzer series, which provides robust audio signaling solutions for demanding environments. The SCE line is characterized by its ability to operate directly from AC or DC control voltages without additional driving electronics, making it suitable for integration into standard industrial control panels.

Alarms, Buzzers, And Sirens Replacement Considerations

Cross-reference sheets indicate potential substitutions for obsolete Murata buzzers. Verify electrical parameters and mechanical footprint before substituting with other Mallory Sonalert models or third-party equivalents.
