With the robust NEARFI-PD… NearFi couplers, you can transmit power (24 V DC / 2 A) and real-time Ethernet data (100 Mbps, full duplex) without contact across a distance in the centimeter range. Furthermore, the specially developed NearFi technology enables latency-free and protocol-independent Ethernet communication. At the same time, the limited wireless range of just a few centimeters also ensures security and permits parallel applications in the tightest of spaces. You can therefore replace wear-sensitive and maintenance-intensive connections and reduce downtimes in your systems.

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.
Do the devices meet the cybersecurity requirements of the Radio Equipment Directive (RED)?
