2489542-3

Overview

The TE Connectivity ALCOSWITCH Switches part number 2489542-3 is a piezo buzzer designed for AC voltage applications. It operates at a rated AC voltage of 240 V and utilizes piezo technology to generate sound. The device produces a single tone with a sound pressure level of 80 dB, measured at 240 V and a distance of 100 cm. This component serves as an audible signaling element within electrical systems requiring high-voltage AC integration.

Feature Summary

• Generates a single-tone audible signal using piezo technology
• Designed for direct operation at 240 V AC
• Provides a standardized sound pressure level of 80 dB

Applications

• Industrial equipment status signaling
• Security system alarms
• Marine vessel warning devices

Procurement Notes

Verify the specific acoustic output requirements against the 80 dB specification at 100 cm distance. Confirm that the operating circuit provides a stable 240 V AC supply compatible with the piezo element. Ensure the mounting environment supports the physical dimensions and thermal characteristics of the buzzer unit during continuous operation.

Selection Notes

Select this component when a high-voltage AC driven audible alarm is required without external drivers. The integrated piezo design eliminates the need for additional power conversion stages. Consider the 80 dB output sufficient for the intended noise floor of the installation area. Verify compatibility with existing panel cutouts and wiring configurations for 240 V AC connections.
