EIAJ-04 Connector for DC Power Supply: A Comprehensive Guide
When it comes to connecting devices that require a specific DC power supply, such as a Comcast/Xfinity modem-router, finding the right connector can be a challenge. In this article, we will dive into the details of the EIAJ-04 connector, its characteristics, and how to successfully integrate it into your power supply system.
Understanding the EIAJ-04 Connector
The EIAJ-04 connector is a specific type of connector used in the telecommunications industry, particularly for power supplies in devices like modems and routers. The connector has a unique design that ensures a secure and reliable connection, with a barrel tip and a center core pin, which are essential for proper power delivery. The dimensions of the barrel tip for the EIAJ-04 connector are specifically 5.5 OD (outside diameter) x 3.5 ID (inside diameter) x 9 L (length).
Narrowing Down the EIAJ-04 Connector
After thorough research, the EIAJ-04 connector can be identified as the EIAJ-04 or EIAJ-04TR connector. The EIAJ-04TR, also known as EIAJ-04, is a standard in the telecommunications industry and is predominantly used for power supplies in devices such as modems and routers. This specific connector can be found in various applications, including the Comcast/Xfinity modem-router, which requires a 12V, 4.6A power supply.
Updating the Connection
After further research and exploration, we were able to find a suitable connector to test. The BiXPower CNT-C2 connector was selected due to its compatibility with the EIAJ-04 requirements. We conducted a successful test and found that the CNT-C2 connector from BiXPower worked flawlessly with the 12V, 4.6A power supply, ensuring a reliable and secure connection for the modem-router.
Ensuring Quality DC Power Supply
Once you have identified the correct connector, it is crucial to ensure that the DC power supply is well-regulated and protected from transient voltage spikes. Transients can damage sensitive electronic components, including the modem-router. Therefore, it is imperative to verify that the power supply is certified and tested to withstand such conditions.
Alternative Solutions
If you are struggling to find the exact connector, one of the easiest solutions is to purchase a generic power supply with changeable tips and adjust it to your specific requirements. Alternatively, you can consider contacting Comcast or Xfinity directly for any part numbers or specific connectors required for their devices.
Conclusion
To summarize, finding the right connector for a 12V, 4.6A DC power supply is crucial for the reliable operation of a Comcast/Xfinity modem-router. The EIAJ-04 connector, specifically the BiXPower CNT-C2, has proven to be a suitable and reliable solution. Additionally, ensuring that your DC power supply is well-regulated and protected from transients is essential for the longevity of your device.
Key Takeaways
EIAJ-04 connector is a standard used in telecommunications, particularly for power supplies in modems and routers. Using a suitable connector and ensuring the DC power supply is well-regulated and protected from transients. Contacting Comcast or Xfinity for any specific connectors or part numbers they require.Frequently Asked Questions
