  • USB 3.0 5Gbps data transfer moves large files quickly

M20 Locking IP68 Adapter

The Fervit M20 adapter joins two USB Type-A cables into a single link, providing a waterproof connection rated to IP68 when mated or capped. It targets installers who need a sealed pass-through for enclosures, marine gear, or industrial controllers where moisture and dust are present.

Sustained 5 Gbps throughput

The coupler complies with USB 3.0 Super-Speed at 5 Gbps and remains backward compatible with USB 2.0 Hi-Speed at 480 Mbps and USB 1.1 Low-Speed at 1.5 Mbps. Potting inside the housing protects the contacts from water intrusion even if a cable sheath is damaged or a cap is left off during long runs.

Sealed housing with no active cooling

Because the unit contains no moving parts or active electronics, it draws no power of its own and generates no heat or noise. The locking M20 shell stays watertight in wet environments such as warehouses or marine decks, and the corrosion-resistant finish prevents rust without requiring maintenance.

Not for buyers needing longer reach

This adapter only bridges two existing cables; it does not extend signal distance beyond standard USB limits or add repeater functionality. Users who require active signal boosting, fibre-optic extension, or a different connector type such as USB-C will need a separate solution.

Questions about this item

Does the IP68-rated M20 locking adapter generate noticeable heat or draw extra power during continuous all-day use?

The passive M20 locking adapter adds no active components, so it produces no measurable heat and draws no additional power beyond what the connected USB 3.0 devices require.

What cables or devices must I already have to use this USB-A female-to-female coupler?

You need two standard USB-A male cables — one from the host and one to the peripheral — because the adapter only provides two USB-A female ports.

Will the 5 Gbps-rated M20 adapter work reliably with older USB 2.0 or USB 1.1 peripherals I keep?

Yes, the coupler is backward-compatible with USB 2.0 at 480 Mbps and USB 1.1 at 1.5 Mbps, so legacy devices function normally through it.
