RJ-45 male wire connector Hirose H7540.12-50, grey, pack of 50

Hirose H7540.12-50 pack contains 50 RJ-45 male wire connectors in grey intended for terminating Ethernet cables. These modular connectors are suitable for creating new network cables or repairing damaged terminations. Each connector is molded to accept standard 8P8C wiring and provides a compact interface for twisted-pair copper conductors, allowing reliable signal transmission for typical LAN installations.

Advantages

The grey RJ-45 male connectors offer uniform dimensions and consistent contact alignment to simplify batch cable assembly. Their molded housing provides strain relief and helps maintain conductor position during crimping. Supplied in a pack of 50, the set reduces repeated purchasing and ensures installers have a ready supply for on-site work. The connectors are compatible with common crimp tools and standard Ethernet cable types, enabling straightforward integration into existing workflows.

Suitable for

• Manufacturing and field assembly of Cat5e/Cat6 network cables
• Repairing or reterminating damaged RJ-45 plugs on patch cords
• On-site network maintenance by installers and technicians
• Small-scale cabling projects and spare parts inventory

Key specifications

• Connector type: RJ-45 male (8P8C) modular plug
• Color: grey
• Pack quantity: 50 pieces
• Compatible conductor format: standard twisted-pair copper wires
• Housing: molded plastic with integrated strain relief
• Intended cable categories: suitable for commonly used Ethernet categories (e.g., Cat5e, Cat6) when used with appropriate cable

How to use

Prepare the cable by stripping the outer jacket to expose the twisted pairs, untwist and align conductors to the required wiring scheme (TIA/EIA 568A or 568B), and trim to the proper length. Insert the aligned conductors fully into the connector until the jacket seats against the plug’s strain relief. Use a compatible crimping tool to press the connector’s contacts onto the conductors and secure the housing. After crimping, inspect the termination for correct conductor order and secure seating before use in network applications.

Recommendations

For reliable performance, use an appropriate crimping tool designed for RJ-45 modular plugs and verify cable category compatibility. Test each terminated cable with a cable tester to confirm continuity and correct pair mapping before deploying in live networks.
