RJ45 connector cat 6,(10ps) which is commonly used for Ethernet cables. You can find various types and packs of RJ45 cat 6connectors  (10ps)-Silver

They are used to connect network devices like computers, routers, switches, and other network equipment via Ethernet cables, facilitating data and power transmission (via Power over Ethernet, PoE).

Structure:

An RJ45 connector is a modular plug typically found at the end of Ethernet patch cables, containing eight golden contacts (pins) for the eight wires within the cable.

Standards:

There are two main wiring standards for RJ45 connectors: T568A and T568B, which define the arrangement of the eight wires within the connector.

Advantages:

They are widely used and standardized, cost-effective, easy to connect and disconnect, and can support high speeds (e.g., up to 10 Gbps with Cat6a).
