SCE120SA3DL1B is listed in the Alarms, Buzzers, And Sirens range at ChipApex. The manufacturer field lists Mallory Sonalert Products Inc.. Its product description is BUZZER PIEZO 42.85MM PNL MNT. Review the specifications below when checking this part for your BOM.
The SCE120SA3DL1B is an industrial-grade audible alarm from the SCE series by Mallory Sonalert. It operates on a voltage range of 30-120VAC and draws 40 mA current. The device emits a continuous tone at 3 kHz with a soft sound profile. Its operational pattern consists of one minute of activation followed by a constant state. This component is designed for panel mounting applications requiring reliable audio signaling in industrial environments.
Verify the exact suffix configuration against the manufacturer datasheet to ensure the correct delay and continuous operation parameters are met. Confirm that the operating voltage range aligns with the system power supply specifications before integration. Check for RoHS compliance documentation if required by project standards.
Select this model when a soft volume level is required to reduce auditory fatigue while maintaining clear signaling. The specific timing sequence of one minute followed by continuous operation distinguishes it from standard continuous or intermittent alarms. Ensure the installation environment supports the specified voltage input range.
This unit belongs to the SCE series of audio indicators, which includes various piezo buzzers and speakers. The series offers expanded options for surface-mounted technology and audible alarms. It serves as a specialized solution within the broader portfolio of Mallory Sonalert transducers and indicators.
Consult the official Mallory Sonalert cross-reference guide for verified substitutes. Generic industrial buzzers may not replicate the specific soft tone characteristics or the precise one-minute-to-continuous timing sequence.
