Black Box Corporation CAT5EJ-WH Keystone Jack White 22-26 AWG

White CAT5e Keystone Jack

The Black Box CAT5EJ-WH is a white Category 5e keystone jack designed for structured cabling installations. It accepts both stranded and solid conductors from 22 to 26 AWG. The jack meets or exceeds the relevant industry standards for twisted-pair connectivity. It suits installers who need a standard-compliant termination point for network cables.

Tool-Compatible Punchdown Design

The jack features a 110-style IDC termination that also works with Krone punchdown tools. This dual compatibility lets technicians use the tool already in their kit without buying a dedicated blade. Flash gold plating on the contacts resists oxidation and maintains low resistance over repeated mating cycles. The lightweight body weighs only 0.03 units and snaps into standard keystone wall plates or patch panels.

Category 5e Rating Limits Bandwidth

This component is rated for Category 5e performance, so it supports Gigabit Ethernet but not the higher frequencies required for 10 Gigabit links over copper. Buyers planning 10 GBASE-T runs must select a Category 6A or higher jack instead. The white colour helps identify port types in dense patch panels. It is not a shielded module, so environments with strong EMI need a screened alternative.
