WST-0905S

Alarms, Buzzers, And Sirens Overview

The WST-0905S is a 5V internally driven magnetic buzzer manufactured by Soberton Inc. It features a 9.6mm diameter design with through-hole PC pin termination. The device operates at a frequency of 2.73kHz and produces a sound pressure level of 83dB at 5V measured at 10cm. It draws a current of 35mA and supports a voltage range of 4 to 6V. The component is washable and utilizes a single-tone operating mode.

Alarms, Buzzers, And Sirens Feature Summary

• Internally driven magnetic technology for simplified circuit integration
• Washable construction suitable for standard PCB assembly processes
• Through-hole mounting with PC pins for secure mechanical attachment

Alarms, Buzzers, And Sirens Applications

• Electronic equipment status indication
• Alarm systems requiring audible alerts
• Consumer appliance signaling

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix or variant against official Soberton documentation to ensure compatibility with required acoustic output and electrical ratings. Confirm that the through-hole footprint matches the target PCB layout. Ensure the washable specification aligns with the manufacturing process requirements, particularly regarding exposure to cleaning agents during assembly.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when an internally driven solution is preferred to reduce external driver complexity. The 5V rating and 35mA current draw suit low-power digital logic interfaces. Consider the 83dB SPL for environments requiring moderate audibility. The washable feature is critical if the assembly line utilizes aqueous cleaning methods without damaging the unit.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the Soberton Inc. family of magnetic buzzers and sirens. It is designed as a direct replacement for similar 5V through-hole magnetic buzzers in existing designs. The internal drive circuit distinguishes it from passive buzzers, allowing direct connection to microcontroller GPIO pins or simple transistor drivers.

Alarms, Buzzers, And Sirens Replacement Considerations

Check datasheets for alternative models with identical 5V operation and 2.73kHz frequency. Verify that substitute parts maintain the same 9.6mm diameter and through-hole pin spacing to fit existing footprints. Ensure acoustic performance metrics are comparable for the intended application environment.
