In maintenance-intensive applications, such as tool changes on robots, you can easily replace wear-prone and maintenance-intensive connections with NearFi couplers, thus minimizing downtime costs.
NearFi couplers – contactless power and data transmission
NearFi is the new contactless real-time transmission technology from Phoenix Contact. Thanks to protocol-independent Ethernet communication, it offers flexible application options for any Ethernet protocol.
With NearFi couplers, power (24 V, 2 A) and real-time Ethernet data (100 Mbps, full duplex) can be transmitted across an air gap of a few centimeters. This allows you to use this technology to replace wear-prone connections and slip rings in industrial applications, while minimizing costly outages.
- Contactless, and therefore no wear and no maintenance
- Protocol-independent and latency-free Ethernet real-time communication
- High power in a compact housing
- Flexible – a high degree of freedom when it comes to installation due to flexible proximity options
- All-around visible diagnostics with LED ring on the housing
Ethernet in real time
The power and data couplers transmit Ethernet data up to 100 Mbps in real time. At the same time, the couplers are fully protocol-transparent, meaning that all conventional Ethernet protocols can be used.
In addition, the couplers also transmit power inductively, and can therefore supply other end devices such as I/O stations, switches, etc., with power without the need for contact.

In the demo, we’ll show you how to minimize costly outages by simply replacing wear-prone connections or slip rings in industrial applications with the NearFi coupler.
NearFi couplers resist dust and dirt
Where conventional connection technology reaches its limits due to space and movement restrictions, vibrations, dust, dirt, rotation, and frequent contacting, NearFi enables wear-free communication across an air gap of a few centimeters. Moreover, transmission through non-metallic materials such as glass, plastic, and wood is possible, which opens up a variety of application possibilities.
With robust IP65 housings featuring M12 connections for Ethernet and power, you can also use the NearFi couplers in demanding environments.
Your advantage: Universal in application.
High degree of mounting freedom with flexible proximity options
In contrast to standard connector solutions, the NearFi couplers can be positioned to face each other from any direction, and even rotating in relation to each other. Furthermore, the couplers do not need to be position precisely opposite each other, but can face each other with an offset, or at a tangential angle.
The couplers can be mounted flexibly with the universal mounting options. They can be mounted via the mounting flange using M5 screws or via the inside thread with M6 screws.
Your advantage: Reduced degree of precision required for the mechanical movement of two independent system parts.
Easy commissioning and diagnostics
In principle, two devices are always necessary for transmission: a base coupler and a remote coupler. The couplers do not need to be configured and are as easy to use as a connector. A signal is issued via an integrated alignment aid once the devices are optimally coupled.
The all-around visual signaling with bright LEDs indicates the operational readiness of the coupling link in all spatial directions. The couplers are diagnosed by a higher-level control system via a digital output. The remote coupler is switched on and off at defined intervals with a digital input on the base coupler.
Typical NearFi coupler fields of application
Communicate without contact between workpiece carriers and processing stations with NearFi couplers. Replace slip rings on turntables and rotary tables with wear-free couplers.
Install NearFi couplers quickly and easily on your automated guided vehicle system (AGV) and transmit power and data between charging stations and AGVs without contact.
Use NearFi couplers for contactless docking between robot and workstation and replace wear-prone connectors.
Use NearFi couplers for communication in cleanroom systems. With contactless transmission, you can avoid particle contamination on connections.
NearFi couplers in use during a robot tool change
Especially in applications such as robot tool changes, the service life of connectors is limited. During robot tool changes, connections are often plugged and unplugged up to several hundred times per day.
The contacts may become damaged, dirty, or misshapen. This leads to unplanned or unforeseeable production stoppages and regular maintenance intervals. The costs for this can quickly run into the millions. Contactless communication with NearFi couplers is a quick remedy for this.
