Connettore RJ-45 Hirose H7641.5-100, giallo/rosso, 100 pz.

Hirose H7641.5-100 is a pack of 100 RJ-45 male wire connectors in yellow and red designed for terminating Ethernet and network cables. These connectors are intended for use in network assembly and cabling tasks where a compact, colour-coded solution is needed to create or repair patch leads and structured cabling. The design supports a standard RJ-45 interface and is suitable for typical copper twisted-pair data cables.

Advantages

The connectors come in two contrasting colours to simplify identification and organisation of multiple cables during installation and maintenance. Supplied in a bulk pack of 100 pieces, they provide a cost-effective option for larger cabling jobs. The RJ-45 male format offers compatibility with common network jacks and patch panels, enabling straightforward termination and quick replacement of damaged plugs. The construction is focused on practical use in field or workshop environments where repeated terminations and visible colour marking are useful.

Suitable for

• Creating and repairing Ethernet patch cables
• Structured cabling installation and testing
• Colour-coded network cable management
• Workshops, field service, and bulk cable assembly

Key specifications

• Connector type: RJ-45 male plug compatible with standard 8P8C sockets
• Pack quantity: 100 pieces
• Colours: yellow and red (colour-coded finishes)
• Intended cable type: copper twisted-pair Ethernet cables (typical UTP/STP)
• Application: termination of patch leads and structured cabling

How to use

Strip the outer jacket of the Ethernet cable to expose the twisted pairs, untwist and align the wires according to the chosen wiring standard (TIA/EIA 568A or 568B). Insert the wires fully into the RJ-45 male connector so each conductor seats in its corresponding contact slot. Use an appropriate crimping tool to compress the connector onto the cable, ensuring a secure mechanical and electrical connection. After crimping, visually inspect the connection and test continuity and signal integrity with a cable tester.

Recommendations

For reliable results, use connectors together with a compatible crimping tool and verify cable pair order before crimping. Choose the colour coding to match your site’s cable management scheme, and perform continuity and performance tests after termination to confirm correct assembly.
