SCE120MA3DP3B

Alarms, Buzzers, And Sirens Overview

The SCE120MA3DP3B is an internally driven piezoelectric buzzer from the SCE series by Mallory Sonalert Products Inc. It operates on AC input within a voltage range of 30 to 120V and draws 40mA of supply current. The device produces a medium loudness sound at 75dB @ 48V, 61cm with a frequency of 3kHz. It features a slow double pulse operating mode and utilizes terminal block connections for panel mounting.

Alarms, Buzzers, And Sirens Feature Summary

• Internally driven piezoelectric technology for direct AC connection
• Slow double pulse audio output pattern
• Panel mount construction with terminal block termination

Alarms, Buzzers, And Sirens Applications

• Industrial machinery status indication
• Control panel alarm signaling
• Equipment fault detection systems

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific acoustic output level and pulse timing against the official datasheet for your application requirements. Confirm that the 30-120V AC input range matches your system voltage. Ensure the terminal block connection type is compatible with your wiring infrastructure before procurement.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when an internally driven solution is required for AC voltages between 30V and 120V. The slow double pulse pattern distinguishes it from continuous or fast-pulse variants. Verify that the 75dB acoustic output meets the ambient noise requirements of the installation environment.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the SCE series of industrial buzzers designed for robust performance in demanding environments. The manufacturer specifies a wide operating temperature range suitable for various industrial settings. The series offers multiple acoustic patterns and voltage options to suit different signaling needs.

Alarms, Buzzers, And Sirens Replacement Considerations

SCE120LA2DP3B provides similar functionality but operates at 2kHz with a different pulse rate. SCE120XA3DP2B offers higher loudness at 105dB with a fast double pulse. Verify electrical compatibility and acoustic requirements before substituting.
