With the robust NEARFI 2000 NearFi couplers, you can transmit real-time Ethernet data (100 Mbps, full duplex) without contact across distances of up to 10 cm. The couplers do not need to be configured and are ready for immediate use. The specially developed NearFi Technology enables latency-free and protocol-independent Ethernet communication. At the same time, the limited wireless range ensures security and permits parallel applications in the tightest of spaces. The NearFi couplers can be brought together from any direction or in rotation. They can face each other with an offset or at a tangential angle. You can therefore replace wear-sensitive and maintenance-intensive connections and reduce downtimes in your systems. The IP65 devices are connected using M12 push-pull fast-connection technology (L/D-coded).

Frequently asked questions
When do I use the A-coded device variants (NEARFI PD, NEARFI P, NEARFI D)?
The A-coded device variants can be used as replacements in existing systems and applications. The A-coded devices are incompatible with the L-coded devices (NEARFI 2xxx).
When do I use the L-coded device variants (NEARFI 2000, NEARFI 200/300, NEARFI 2200)?
The L-coded device variants can be used for new projects. The L-coded devices enable doubling of the range during data transmission, power duplication through parallel connection, and other functions. The L-coded devices are incompatible with the A-coded devices.
