RFID locking system for modular machine connectors

igus has introduced an RFID locking solution designed for the Module Connect modular connector system, aimed at improving the security of electrical and media connections in industrial machinery.

In many production environments, unintended intervention at connector interfaces—particularly at cable chain connection points—can lead to equipment downtime, additional service operations and increased maintenance costs. The new RFID lock is designed to prevent unauthorized access to these interfaces and protect sensitive machine connections.

RFID-based protection for industrial connectors
The RFID lock has been developed as a retrofit add-on for the Module Connect interface used in cable chain systems. The device clips directly onto the existing connector interface and secures it mechanically with a metal locking pin.

Access is controlled through RFID authentication. The connector can only be opened with an authorized RFID card, preventing unqualified personnel from disconnecting critical machine connections.

The system includes an integrated microcontroller that verifies RFID credentials and can optionally record access events. This logging capability supports maintenance documentation, traceability and quality management processes in industrial operations.

Tool-free installation and compact design
The RFID lock features a compact housing and can be installed without tools, enabling quick integration into existing machines or production lines. Because it is designed as a retrofit component, the solution can be added to installed systems without modifications to the underlying connector interface.

This approach allows manufacturers to enhance connection security while minimizing downtime during installation.

Modular connector system for energy, data and media
The RFID solution complements the Module Connect modular connector system, which enables multiple cables and media lines to be integrated into a single connection interface.

The system can combine different types of connections—including power cables, bus systems, fiber-optic lines and pneumatic hoses—within one structured module. Instead of connecting multiple individual plugs, operators can establish a complete connection with a single plug-in operation.

According to igus, this architecture can reduce installation time by up to 80 percent compared with conventional wiring methods.

Flexible configuration for machine integration
Module Connect uses modular housings that can be configured individually with electrical, optical or pneumatic inserts. Each housing can accommodate up to four inserts and can be combined with additional modules to create a customized interface.

The compact design supports high contact density and is suitable for machines with limited installation space. Energy, data and media lines converge at a single connection point, improving cable management and reducing the risk of wiring errors.

Because all components can be installed without tools, system modifications, upgrades or maintenance operations can be implemented quickly. This modular architecture makes the system suitable for both compact machines and large industrial installations where multiple media connections must be integrated efficiently.
