Product Details


You can transmit power (24 V DC / 2 A) and real-time Ethernet data (100 Mbps, full duplex) without contact across distances of up to 10 mm with the robust NEARFI-PD… NearFi couplers. 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.
