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 NearFi is the contactless real-time transmission technology from Phoenix Contact. With protocol-independent Ethernet communication, it offers flexible application options for any Ethernet protocol. NearFi couplers enable power (up to 100 W) and real-time Ethernet data (100 Mbps, full duplex) to 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.
Your advantages:
- 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
Protocol-independent near-field communication in real time
Ethernet in real time
NearFi couplers transmit Ethernet data at a speed of up to 100 Mbps (full duplex) in real time. At the same time, the couplers are fully protocol-transparent, meaning that all conventional Ethernet protocols can be used.
The fast device startup enables use in applications where application-specific functions such as “Fast Startup” are required.
Near-field communication via air gap does not require frequency planning or wireless technology expertise.
Constant power transmission with automatic current equalization
Inductive power transmission
In addition, the couplers transmit power inductively, and can therefore supply other end devices such as I/O stations, switches, etc., with power without the need for contact. A power of 50 W can be transmitted via a NearFi path.
By combining two NearFi paths, the power can be increased to 100 W with automatic current equalization. In addition, application-specific functions such as the transmission of two electrically isolated voltages (US/UA, each 50 W) are also enabled.
NearFi coupler in use
High degree of mounting freedom
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.
Primary and secondary couplers with all-around LED ring for rapid diagnostics
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.
Robust and versatile in use
Resistance to 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 the robust IP66 housing, you can use the NearFi couplers in demanding environments. The M12 connection for Ethernet and power is made via a screw connection thanks to the Duo contour, or quickly and easily with M12 PUSH-PULL fast-connection technology.
Your advantage: universal in application.
Multi-award-winning technology
NearFi couplers set new standards in contactless power and data transmission in the near-field range. They have already received several awards from leading international trade magazines and prestigious industry prizes such as the Hermes Award.
The awards underline the innovative performance and technological progress that the NearFi couplers offer for industrial applications. They also embody the high quality and future security of the technology.
Typical areas of application of NearFi couplers
Communicate contactlessly with movable or rotating system parts using NearFi couplers and avoid production downtimes due to defective connectors or slip rings that are susceptible to interference.
Use NearFi couplers for contactless transmission between the workpiece carrier and the production station and replace wear-prone and maintenance-intensive connectors.
Install NearFi couplers quickly and easily on your automated guided vehicle system (AGVS) and transmit safety-related data contactlessly between the AGVS and production station.
