AS05808PO-WP

Overview

The PUI Audio AS05808PO-WP is a waterproof piezo buzzer designed for audible signaling in harsh environments. It operates at a resonant frequency of 2.7 kHz and delivers a sound pressure level of 85 dB at 10 cm when driven by a 3 VDC supply. The component features a hermetically sealed construction with an IP67 rating, ensuring protection against dust ingress and temporary immersion in water up to 1 meter for 30 minutes. It utilizes a standard two-wire connection interface and is housed in a compact cylindrical package suitable for space-constrained applications requiring reliable acoustic output under wet conditions.

Feature Summary

• Hermetically sealed construction provides robust protection against environmental moisture and dust ingress
• Capable of delivering consistent audible alerts in wet or submerged conditions due to IP67 compliance
• Designed for direct integration into electronic circuits using standard two-wire connections

Applications

• Marine electronics and boat instrumentation panels
• Outdoor industrial control panels exposed to weather elements
• Medical devices requiring sterilization or fluid resistance
• Automotive sensors and warning systems subject to washdowns

Procurement Notes

Verify the specific ordering suffix and voltage rating against the manufacturer's current datasheet before procurement. Confirm that the required operating voltage matches your system design, as variants may exist. Ensure the mounting method aligns with your enclosure design, as mechanical dimensions can vary slightly between production batches. Always request the latest revision documentation to confirm material specifications and compliance status.

Selection Notes

Select this component when environmental sealing is critical for long-term reliability in wet conditions. Consider the 2.7 kHz resonant frequency for optimal human hearing sensitivity in noisy environments. Evaluate the 85 dB SPL requirement against ambient noise levels to ensure adequate audibility. Verify that the physical dimensions fit within the designated housing constraints without compromising the seal integrity during installation.

Part Context

This model belongs to PUI Audio's line of waterproof piezoelectric buzzers, engineered specifically for durability in challenging environments. Unlike standard open-frame buzzers, this series incorporates specialized sealing techniques to maintain acoustic performance while preventing fluid penetration. It serves as a direct replacement for legacy waterproof signaling components in industries where equipment failure due to moisture is a primary concern.

Replacement Considerations

Check for exact dimensional compatibility and terminal configuration when substituting. Verify that the replacement part meets or exceeds the original IP67 rating and acoustic output specifications. Ensure the new component supports the same driving voltage and current requirements to avoid circuit damage or insufficient volume.
