1234232

Overview

The Phoenix Contact NEARFI PD 2A ETH R (1234232) is an inductive coupler designed for non-contact transmission of power and real-time Ethernet data. It delivers 24 V DC at up to 2 A with a maximum range of 10 mm at 55°C or 12 mm at 25°C. The unit supports 100 Mbps full-duplex Ethernet via M12 D-coded connectors, ensuring protocol transparency for industrial standards like PROFINET IRT and EtherCAT. Power is supplied through M12 A-coded connectors. Key electrical features include short-circuit protection, MTTF values ranging from 27 to 115 years depending on conditions, and automatic negotiation capabilities.

Feature Summary

• Enables contactless transfer of 24 V DC power and 100 Mbps Ethernet data within a limited range to ensure safety and allow dense spatial arrangement.
• Provides protocol-transparent communication supporting major industrial Ethernet standards including PROFINET IRT, EtherCAT, and PROFIsafe without latency.
• Features robust IP65 protection and M12 screw connections for reliable operation in demanding industrial environments.

Applications

• Replacing wear-prone mechanical connectors in automated machinery to reduce maintenance downtime.
• Powering and communicating with rotating or moving components where cables are subject to fatigue.
• Integrating sensors and actuators in tight spaces requiring simultaneous power and data transmission.

Procurement Notes

Verify compatibility with the corresponding base unit, such as the NEARFI PD 2A ETH B, as specified in official documentation. Confirm that the application environment temperature does not exceed limits affecting the coupling range. Ensure correct M12 coding (A-coded for power, D-coded for data) during installation. Check for incompatibility with newer NEARFI 2200 series products before procurement.

Selection Notes

Select this model when non-contact transmission of both power and high-speed Ethernet data is required within a small gap. It is suitable for applications needing protocol transparency for various industrial networks. Consider the operating temperature range as it directly impacts the maximum effective coupling distance. Ensure the system design accommodates the specific M12 connector types and alignment tolerances defined by the manufacturer.

Part Context

This component belongs to the NEARFI COUPLER series, which specializes in inductive technology for wireless energy and data transfer. It serves as the mobile or remote unit in a coupled pair, designed to work alongside a stationary base coupler. The series aims to eliminate physical cable wear in dynamic automation systems while maintaining real-time communication integrity.

Replacement Considerations

Officially documented substitutes include compatible base units like the NEARFI PD 2A ETH B. Note that this model is explicitly incompatible with the NEARFI 2200 series. Verify pinout and connector coding matches existing infrastructure before replacement.
