Overview
The AS07708PS-2-WR-R is an electromagnetic speaker transducer manufactured by PUI Audio, Inc. It features a round shape with a ferrite magnet and paper cone. The unit has an impedance of 8 Ohms and a power rating of 4 W. It delivers a sound pressure level of 90 dBA at a self-resonant frequency of 250 Hz. The component utilizes solder lug end termination and frame mount installation style. Physical dimensions are approximately 71 mm in length, 41 mm in width, and 25 mm in height.
Feature Summary
- Water resistant construction for durability in varied environments
- Electromagnetic transduction using ferrite magnet technology
- Frame mount design for secure mechanical integration
Applications
- General purpose audio output devices
- Industrial equipment signaling
- Consumer electronics enclosures requiring water resistance
Procurement Notes
Verify the specific suffix 'WR' confirms water resistance requirements against project specifications. Confirm that the 8 Ohm impedance matches the amplifier output capabilities. Ensure the frame mount dimensions align with the available chassis space. Check current availability status as lead times may vary for this component type.
Selection Notes
Select this model when water resistance is required alongside standard 8 Ohm impedance. Compare the 90 dBA sensitivity against acoustic needs. Consider the 4 W power handling limit relative to drive signals. Evaluate the physical depth constraint of 25 mm against enclosure depth limitations.
Part Context
This part belongs to the AS series of speakers from PUI Audio, Inc. It shares the 77mm diameter form factor with other models like the AS07708PS-2-R but adds water-resistant properties. It differs from the WR variant in its specific environmental protection rating compared to standard electromagnetic speakers in the same family.
Replacement Considerations
AS07708PS-2-R serves as a non-water-resistant alternative within the same series. Verify if the loss of water resistance is acceptable for the application environment before substituting.
