• Internal driver circuitry
• Beep tone output

Applications

• Industrial equipment status indication
• Control panel alarm signaling
• High-voltage AC system monitoring

Procurement Notes

Verify the specific suffix R against the manufacturer datasheet to confirm if it denotes a reel packaging format or a distinct electrical variant. Ensure the input power supply matches the 90-120V AC requirement strictly. Confirm RoHS compliance status through official documentation before integration into regulated assemblies.

Selection Notes

Select this component when a high-decibel audible alert is required for industrial environments. The internal driver simplifies design by removing external oscillators. Verify that the 30.74mm mounting hole dimension fits the enclosure constraints. Ensure the operating environment does not exceed the specified acoustic limits.

Part Context

This part belongs to the ZT series of industrial buzzers designed for robust performance. It serves as a direct replacement for older models requiring similar voltage and acoustic specifications. The series is characterized by reliable operation in demanding industrial settings.

Replacement Considerations

Cross-reference with ZA120LASU2 for similar industrial applications. Verify mechanical fitment and electrical compatibility before substitution.
