Features and Benefits
With the rise of IoT, 5G networks and extreme data rate bandwidth requirements, engineers are now under increasing pressure to maximize signal integrity and connector density. To meet these needs, connectors are required to support high-speed data rates, mitigate the effects of EMI, and protect against voltage spikes and unexpected surges. A range of Molex Modular Jacks and Plugs overcome these challenges by delivering high quality connections capable of high data rates, scaling with changing needs and meeting future requirements.
For high-speed applications, a significant obstacle is maintaining signal integrity, as high-speed data lines are prone to even small amounts of EMI and crosstalk. Molex Modular Jacks and Plugs solve this with the integration of advanced EMI shielding, preventing outside interference from affecting signal quality.
Furthermore, many applications demand increased durability and long-term reliability in harsh conditions, including resistance from moisture, dust and dirt, as well as the need for support through many mating cycles. To meet these demands, Molex Modular Jacks and Plugs are designed with strength and resilience, offering dependable performance and extended product life to support stable, long-lasting connectivity.

Frequently Asked Questions
What is a modular jack?
A modular jack is a standardized connector commonly used in telecommunications and data networking to provide a reliable interface. The RJ45 version is the most common type used for Ethernet connections in local area networks, while the RJ11 type remains standard in telephone systems. Modular jacks are designed to ensure consistent electrical performance, secure mating and easy installation across a wide range of equipment.
What are the different types of modular jacks?
Modular jacks are categorized depending on the shape and number of contacts they have, each being uniquely ideal for different communication systems. Primarily used in Ethernet networking, the most common is the RJ45 jack that supports cable categories from Cat5e to Cat6a. The second most common is the RJ11 jack with six positions but only using 2 to 4 contacts and typically used for analog telephone lines. The RJ12 version uses six contacts to support more complex telecom systems. In applications where these connectors are unsuitable, specialized or custom modular jacks are available for industrial and proprietary applications that require unique configurations or electrical performance.
What factors should I consider when choosing a modular jack?
To select the right connector for an application, engineers must take multiple factors into consideration. To start, the number of contacts and positions will likely be determined if a standard is being used (such as Ethernet), but in unique applications, these will depend on signal and power requirements. Cable compatibility also needs to be considered, along with the speed requirements. This also ties in to shielding requirements, as high-speed cables often need adequate shielding. Environmental considerations and durability also play a considerable role, especially in harsh industrial and commercial environments. Finally, compliance with industrial standard such as TIA and EIA should be evaluated.
Can modular jacks support high-speed Ethernet?
Modern modular jacks are ideal for carrying high speed Ethernet, especially the RJ45 variation, as long as they are paired with the appropriate cable category (for example, Cat6a and Cat7 for 10Gbps) and correctly terminated.
