RJ-45 male wire connector Hirose H7540.4-50, black, pack of 50

Hirose H7540.4-50 is a pack of 50 black RJ-45 male wire connectors designed for terminating Ethernet cables quickly and reliably. Each connector is a standard 8P8C male RJ-45 style contact suitable for creating or repairing network patch cables and custom cable assemblies. The compact plastic housing and gold-plated contacts ensure solid electrical contact and a low-profile connection appropriate for typical Ethernet installations.

Advantages

These RJ-45 male wire connectors offer straightforward hand or crimp-press termination, enabling faster field or workshop cable assembly. The black housing provides a uniform professional appearance and helps visually distinguish cable runs. Durable contact plating improves signal integrity and reduces oxidation over time, while a compact form factor supports cramped patch panels and tight cable routing.

Suitable for

• Termination of CAT5e and CAT6 network patch cables
• Field repairs of damaged Ethernet leads
• Custom cable assembly in workshops and small production runs
• Connecting devices to switches, routers, patch panels, and wall outlets

Key specifications

• Connector type: RJ-45 male (8 positions, 8 contacts)
• Contact finish: gold-plated contacts for improved conductivity and corrosion resistance
• Housing color: black
• Suitable cable types: stranded and solid twisted-pair Ethernet cables (commonly CAT5e/CAT6)
• Package quantity: 50 connectors per pack
• Mounting/termination method: designed for crimp or press termination in compatible tools
• Mechanical form factor: compact, low-profile modular plug

How to use

Prepare the Ethernet cable by stripping the outer jacket to expose the twisted pairs, untwist and arrange the conductors according to the desired wiring standard (T568A or T568B). Trim the conductors evenly and insert them fully into the RJ-45 connector until the cable jacket seats correctly in the plug. Use a compatible crimping or press tool to compress the connector and secure the contacts onto the conductors. After crimping, visually inspect that each conductor reaches the front of the connector and test the assembled cable with a network cable tester to verify continuity and correct pairing.

Usage recommendations

For consistent results, use a crimping tool rated for modular RJ-45 plugs and ensure conductors are trimmed squarely. Select connectors matched to the cable type (solid vs. stranded) where applicable, and perform continuity and pair integrity tests after termination to confirm reliable network performance.
