## Long description

Hirose RJ-45 male wire connector H7540.4-100 in black is a compact modular plug designed for terminating copper Ethernet cables where a standard RJ-45 male interface is required. The connector accepts appropriately prepared UTP/STP cable conductors and provides a conventional 8P8C contact arrangement to connect network devices, patch panels, or cable assemblies. Its small form factor and black finish make it suitable for discreet installations and repairs in structured cabling environments.
Advantages
The connector offers a reliable electrical contact arrangement compatible with common Ethernet wiring schemes, ensuring consistent signal transmission. Its compact design simplifies insertion into jacks and mating housings while reducing bulk in cable runs. Colour coding in black supports visual identification and aesthetic consistency in installations. The part is intended for use with copper twisted-pair cables and provides a straightforward solution for making or repairing RJ-45 terminations.
Suitable for
 Creating or repairing RJ-45 terminations on copper Ethernet cables
 Field or workshop network cable assembly
 Patching and custom-length Ethernet leads for office and data centre use
 Integrating copper network connections into existing structured cabling
Key specifications
 Connector type: modular RJ-45 male (8P8C)
 Colour: black
 Cable compatibility: copper twisted-pair Ethernet cables (UTP/STP)
 Contact arrangement: 8 conductors for standard Ethernet wiring
 Housing: compact modular plug for low-profile installations
How to use
Prepare the Ethernet cable by stripping the outer jacket and arranging the individual conductors according to the desired wiring standard (T568A or T568B). Trim conductors to the appropriate length, insert them fully into the connector so each wire seats into its corresponding contact, and verify the order visually before securing the termination using a compatible crimping or insertion tool. After termination, inspect contacts for full insertion and continuity testing to confirm correct wiring and signal integrity.
Usage recommendations
Use with compatible crimping or insertion tools designed for RJ-45 modular plugs; ensure cable preparation and conductor seating follow the selected wiring standard. Test each terminated cable with a network cable tester for continuity and pair integrity before deployment. For installations in electrically noisy environments, choose shielded cable and connectors rated for STP use when necessary.
