Black Box FMT636-R3-25PAK CAT6 RJ-45 Keystone Jack

Preserve signal integrity at the termination point with a CAT6 keystone jack designed for structured cabling environments that cannot afford rework. Black Box FMT636-R3-25PAK supports GigaTrue CAT6 cables and meets TIA/EIA-568-C.2 requirements, giving infrastructure teams a dependable path for 250 MHz data transmission. Universal wiring and clear T568A/T568B labeling simplify deployment across mixed standards, while the keystone form factor enables fast snap-in installation in patch panels, wall plates, and surface-mount boxes. Gold-plated nose contacts and phosphor bronze contact material help maintain consistent connectivity over repeated mating cycles. IDC contacts use tin plating, and the built-in strain relief supports a cleaner termination under cable movement and handling. For teams standardizing on CAT6 while maintaining compatibility with legacy plant, this jack is backward compatible with CAT5e, CAT5, and CAT3 components. The 25-pack format fits multi-drop projects, refreshes, and staged rollouts where consistency matters more than lowest-cost hardware. When the termination point is part of the performance budget, this is the component to specify.
