PUI Audio Miniature Speaker, 3W Rated Power, 4Ω Impedance - AS04004PO-2-WR-R
This miniature speaker is designed to provide Compact acoustic output for industrial and electronic systems where space and moisture resistance matter. It offers a continuous tone response suitable for signalling and alerting within control panels and portable devices, combining a paper cone diaphragm with a low electrical impedance to deliver audible levels in confined installations.
Features and Benefits:
• 4Ω impedance for straightforward drive with common amplifiers
• 3W rated power enabling clear audible alerts at low supply levels
• 82dBA sensitivity for recognisable sound in noisy environments
• Continuous tone output facilitating steady signalling or alarms
• Water-resistant construction allowing use in damp locations
• Compliant with EU RoHS 2011 and REACH ensuring restricted-substance adherence
• 3W rated power enabling clear audible alerts at low supply levels
• 82dBA sensitivity for recognisable sound in noisy environments
• Continuous tone output facilitating steady signalling or alarms
• Water-resistant construction allowing use in damp locations
• Compliant with EU RoHS 2011 and REACH ensuring restricted-substance adherence
Applications
• Suitable for factory automation alarm and notification panels
• Ideal for handheld diagnostic and test instruments
• Used with control enclosures requiring moisture-tolerant audio
• Can be used for embedded signalling in HVAC systems
• Suitable for low-profile public-address cueing in kiosks

What drive characteristics are needed for optimal performance?
It runs on low-voltage amplifier stages that can supply nominal 3W into a 4Ω load, ensure the drive device limits power to avoid exceeding rated input.
How does the diaphragm material affect response and use?
The paper cone provides natural midrange reproduction and mechanical damping suitable for steady tones, making it appropriate for alerts rather than hi-fi audio.
What approvals affect selection for regulated projects?
The component meets EU RoHS 2011 and REACH chemical restriction standards, supporting procurement for assemblies constrained by those regulations.
How does the speaker behave across its frequency capability?
It is specified up to 20kHz for continuous-tone signalling, so it supports the human-audible range needed for clear alert tones.
