BECKHOFF EK1100 For Parts EtherCAT Terminals EtherCAT Coupler

Product Overview

This listing is for a Beckhoff EK1100, the industry-standard EtherCAT Coupler designed to bridge the EtherCAT protocol with the Beckhoff EL/ES series EtherCAT Terminals. Offered strictly For Parts / Not Working, this unit is a vital resource for automation engineers and repair technicians who need to salvage authentic Beckhoff components—such as the internal logic board, E-bus connectors, or the rugged plastic housing—to repair and maintain high-speed industrial I/O systems.

Potential Salvageable Components

• EtherCAT Interface Ports: Two RJ45 sockets (Input/Output) that can be harvested to repair units with broken plastic tabs or damaged internal pins.
• E-Bus Interface: The side-mounted gold-plated contacts that provide power and data to adjacent terminal modules.
• Internal CPU/Logic Board: Contains the specialized EtherCAT ASIC and communication controllers unique to Beckhoff’s high-speed architecture.
• Front Bezel & Status Windows: Clear plastic light-pipe components for the "Run," "Link/Act," and "Error" LEDs.
• Chassis & Mounting Clip: The high-quality plastic housing and the orange DIN rail release clip, useful for replacing physically damaged or cracked shells.

Item Condition (For Parts / Not Working)

• Functional Status: Not Working. This coupler is being sold as-is for salvage. Common reasons for this status include failure to establish an E-bus link, "Bus Error" LED remaining active, or no response from the EtherCAT master.
• Physical State: Shows signs of industrial use, including minor scuffs or dust. Some terminal markings may be present from its previous installation.
• Warning: No functional guarantee is provided for the internal electronics. This is a Non-Returnable listing intended for professional repair use or as a source for mechanical spares.
• Visual Reference: Please examine the high-resolution images carefully to verify the specific hardware revision; the unit pictured is the exact EK1100 you will receive.
