RJ45 Female-to-Female Connector In S-Impuls 71220-8M Metallic

Inline RJ45 female-to-female coupler by In (S-Impuls model 71220-8M) with a metallic housing designed to join two RJ45 patch cables in a straight-through connection. This passive coupler maintains pin-to-pin continuity so that network signals pass between Cat5, Cat5e and Cat6 cables when both ends use compatible RJ45 connectors. The metallic shell provides mechanical strength and shielding where connected cables and connectors match the same wiring and grounding conventions.

Advantages

The metallic enclosure offers enhanced mechanical durability compared with plastic couplers and contributes to improved electromagnetic shielding in environments where interference may be present. Its inline, gender-coupling design allows quick extension of existing Ethernet patch cords without re-terminating cables or changing wall plates. The passive construction requires no power or configuration and preserves straight-through wiring for typical Ethernet applications.

Suitable for

• Extending Ethernet patch cables in office and home network setups
• Temporary or ad-hoc network links for events, testing, or repairs
• Joining compatible Cat5/Cat5e/Cat6 patch cords where straight-through wiring is required
• Situations requiring a compact, shielded inline connection between two RJ45 plugs

Key specifications

• Connector type: RJ45 female-to-female inline coupler
• Compatibility: Cat5, Cat5e, Cat6 patch cables with matching RJ45 plugs
• Construction: metallic housing for strength and shielding
• Wiring: straight-through/passive pin continuity
• Use: passive, no power or electronics required
• Shielding: screened/metal housing to reduce EMI where system grounding is present

How to use

Ensure both Ethernet patch cables to be joined use compatible RJ45 plugs and the same wiring standard (T568A or T568B). Insert one patch cable plug into each end of the coupler until they seat securely. Confirm the connection by checking link status on network devices or by testing continuity with cable testers if required. For shielded installations, ensure cable drains or shields are properly connected to maintain continuity through the metallic housing.

Recommendations

Use the coupler for short, temporary or convenience extensions rather than permanent structured cabling. Avoid placing the inline coupler in locations subject to excessive tension, moisture, or physical strain. For shielded cable runs, verify proper grounding of cable shields to benefit from the metallic housing's EMI protection. When higher performance or longer permanent runs are needed, consider using a single continuous, properly terminated cable instead of multiple joined segments.
