Overview
The CAC32-02W90-16-1X is a general-purpose speaker manufactured by Challenge Electronics. It features a 4 Ohm impedance and a power handling capacity of 2 Watts. The frequency response ranges from 720 Hz to 20 kHz, with a self-resonant frequency of approximately 900 Hz. The unit includes an enclosure and has a top square form factor. Key physical dimensions include a diameter of 32.0 mm and a height of 16.0 mm. It offers a sensitivity of 104 dB and carries an IPX8 rating for the front face.
Feature Summary
- Includes integrated enclosure for simplified installation
- Top square design with square frame geometry
- IPX8 rated front face for environmental protection
Applications
- General purpose audio output devices
- Enclosed electronic assemblies requiring compact speakers
- Applications necessitating IPX8 front-face protection
Procurement Notes
Verify the specific suffix codes against official manufacturer documentation to ensure correct impedance and power ratings. Confirm that the required enclosure type matches the standard included configuration. Cross-reference the IPX8 rating requirements with the specific mounting orientation to ensure the front face protection remains effective in the final assembly.
Selection Notes
Select this component when a compact, enclosed speaker solution is required with high water resistance on the front face. The 4 Ohm impedance suits standard low-voltage audio circuits. Ensure the application space accommodates the 32.0 mm diameter and 16.0 mm height constraints while allowing for the top square mounting profile.
Part Context
This model belongs to the Challenge Electronics CAC series of general-purpose speakers. These components are designed for integration into various consumer and industrial electronic devices. The series emphasizes compact form factors and robust construction suitable for diverse environmental conditions.
Replacement Considerations
Direct substitutes must match the 4 Ohm impedance, 2 Watt power rating, and 32.0 mm diameter. Verify that any replacement maintains the IPX8 front-face rating and similar frequency response characteristics.
