W-18-1

Overview

The East Electronics W-18-1 is a piezoelectric buzzer designed for audible signaling applications. It operates within a voltage range of 6 to 15 volts, with typical performance specified at 12 volts. The device generates an acoustic output of 105 decibels measured at a distance of one meter. Its operating frequency falls between 2.5 kHz and 4 kHz. Electrical consumption at the nominal voltage is approximately 350 mA. The unit features integrated wire leads for direct connection.

Feature Summary

• Generates high-intensity audible alerts using piezoelectric technology
• Includes pre-attached wire leads for simplified circuit integration
• Operates reliably across a wide DC voltage spectrum

Applications

• Industrial machinery status indicators
• Consumer appliance alarm systems
• Automotive warning signals

Procurement Notes

Verify the specific datasheet version for the W-18-1 to confirm exact acoustic measurements and electrical tolerances. Ensure the receiving circuitry supports the 350 mA current draw at 12V. Confirm that the wire lead length meets the mechanical requirements of the assembly. Cross-reference the voltage range specifications against the system power supply to guarantee stable operation without damage.

Selection Notes

Select this component when a high-decibel audible alert is required in compact spaces. The integrated wire leads eliminate the need for additional connectors or soldering pads, reducing assembly time. The wide voltage tolerance allows flexibility in power supply design. Consider the physical size constraints and mounting orientation relative to the sound propagation direction.
