RJ45 – 8 Position Modular Plug ( 25 PACK )

The RJ45 (Registered Jack 45) is the standard 8-position, 8-contact ( $8P8C$ ) modular plug used universally for terminating $twisted-pair$ Ethernet cables in a Local Area Network (LAN). This small, clear plastic connector features eight metallic contacts that pierce the insulation and make electrical contact with the eight individual copper wires inside an Ethernet cable, such as Cat5e or Cat6. When properly crimped onto the cable, the RJ45 plug allows the cable to securely lock into the corresponding $8P8C$ jack found on devices like computers, routers, switches, and wall plates, facilitating reliable data transmission and typically featuring $50 micron$ gold-plated contacts for enhanced conductivity and corrosion resistance.

Technical Specification

RJ45 Modular Plug

Parameter	Specification (Typical)	Function/Detail
Connector Type	$8 P 8 C$ Modular Plug (Male)	8 Position, 8 Contact. The standard physical configuration for Ethernet.
Compatibility	Cat5e, Cat6 (and often Cat6a/7)	Must match the cable’s performance category and insulation thickness.
Contact Plating	$50 Micron$ Gold	Essential for maximizing conductivity and preventing corrosion, ensuring a reliable connection.
Contact Configuration	3-Prong or 2-Prong	Refers to the blades used to make contact with the wire. 3-prong is better for solid and stranded wire compatibility.
Housing Material	Polycarbonate (PC)	Clear, durable plastic that provides the housing structure and allows for visual confirmation of wire order.
Max Wire O.D.	$\approx 1.05 mm$ to $1.20 mm$	The maximum outer diameter of the individual insulated wire the plug’s channels can accept. Varies greatly between Cat5e and Cat6 plugs.
Durability	$750 Cycle$ Minimum	The guaranteed number of insertion and removal cycles the connector can withstand.
Flammability Rating	UL $94 V- 2$ or $94 V- 0$	Standard industry safety rating for resistance to ignition and self-extinguishing properties.
Wiring Standard	EIA/TIA $568 A$ or $568 B$	The standardized pin-out configurations that must be followed when terminating the cable.
