UC-09-628-W

Overview

The UC-09-628-W is a panel mount chime alarm manufactured by Floyd Bell Inc. It belongs to the Audiolarm II series and features an internally driven piezo driver circuit. The device operates on a DC input voltage range of 5 to 25 volts. It produces a sound pressure level of 70 dB at 5 volts measured from a distance of 61 cm. The operating frequency is 2.9 kHz. Electrical current consumption ranges from 5 to 25 mA depending on the applied voltage. The unit is designed for top port mounting and has an IP68 rating, providing dust tight and waterproof protection. It functions within a temperature range of -20°C to 65°C.

Feature Summary

• Internally driven piezo technology for direct DC operation
• IP68 rated enclosure ensuring dust tight and waterproof performance
• Panel mount design with wire lead termination

Applications

• Industrial equipment status indication
• Control panel audio signaling
• Enclosed machinery chime alarms

Procurement Notes

Verify the specific suffix configuration against the manufacturer's official datasheet to ensure compatibility with required voltage and acoustic specifications. Confirm that the IP68 sealing integrity meets the environmental requirements of the installation site. Check for any recent updates to the Audiolarm II series documentation regarding pinout or mounting dimensions before finalizing procurement orders.

Selection Notes

Select this component when a robust, waterproof audio indicator is required for panel mounting applications. The internally driven nature simplifies circuit design by eliminating the need for external oscillators. Ensure the available space accommodates the specified diameter and height constraints while maintaining access to the top-mounted ports for sound projection.

Part Context

This part is part of the Audiolarm II family from Floyd Bell Inc, which specializes in piezoelectric signaling devices. The series is known for combining high reliability with environmental sealing capabilities. The UC-09-628-W specifically targets applications requiring durable audio alerts in harsh conditions where standard open-frame buzzers would fail due to moisture or dust ingress.

Replacement Considerations

Consult official substitution guides for equivalent IP68 rated piezo chimes. Verify that replacement parts match the 5-25V DC operating range and 2.9 kHz frequency to maintain system compatibility.
