Component Specifications

Definition
An 8P8C modular connector commonly known as RJ-45, designed for terminating twisted-pair Ethernet cables in network interface cards. It provides physical interface for Category 5/6/6a/7 cables, supporting data transmission speeds from 10 Mbps to 10 Gbps depending on cable specifications and NIC capabilities. The connector features gold-plated contacts for reliable electrical connection and plastic housing with locking tab for secure cable retention.
Working Principle
Electrical signal transmission through eight copper contacts arranged in specific pinout configuration (T568A/T568B). The connector establishes physical and electrical connection between twisted-pair cable conductors and NIC circuitry, enabling differential signaling that reduces electromagnetic interference. The modular design allows for easy cable replacement and maintenance.
Materials
Copper alloy contacts with 50μ" gold plating over 100μ" nickel underplate, UL94V-0 rated thermoplastic housing (typically polycarbonate or ABS), phosphor bronze contact springs, stainless steel locking tab.

Frequently Asked Questions

What is the difference between RJ-45 and 8P8C connectors?

RJ-45 is the common name for the 8P8C modular connector used in Ethernet networks. Technically, 8P8C describes the physical configuration (8 positions, 8 contacts), while RJ-45 refers to the telecommunications standard for this connector type.

Can RJ-45 connectors support PoE (Power over Ethernet)?

Yes, standard RJ-45 connectors are designed to support PoE applications up to 60W (802.3bt). The gold-plated contacts and proper insulation ensure reliable power transmission alongside data signals.

What maintenance is required for RJ-45 connectors in industrial environments?

Regular inspection for dust/debris accumulation, contact oxidation check, and verification of locking tab integrity. Use contact cleaners specifically designed for gold-plated connectors when necessary.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
