Function and Working Principle
The Siemens 6AG1901-1BB20-7AA0 provides a physical connection between an Industrial Ethernet twisted-pair cable and an RJ45 network interface. It is designed to simplify cable termination and support reliable data transmission in industrial communication systems.
1. Industrial Ethernet Cable Termination
The connector uses integrated cut-and-clamp contacts for the industrial Ethernet cable side. These contacts are designed to establish electrical connections with the conductors of a compatible IE FC TP 2×2 cable.
The FastConnect system supports field assembly and helps simplify the termination process. Correct cable preparation and conductor positioning remain essential for achieving a stable connection.
2. RJ45 Network Connection
The opposite side of the connector provides a standard RJ45 interface. This allows the terminated industrial cable to connect to compatible Ethernet ports on industrial communication equipment.
Typical connected devices may include industrial Ethernet switches, PLC communication interfaces, network modules, and other compatible automation equipment.
The connector itself does not perform switching, routing, or signal processing. Its role is to provide the physical network connection.
3. 90-Degree Cable Outlet
The 90-degree cable outlet provides a right-angle cable routing arrangement. This design can be useful in compact control cabinets, equipment enclosures, and installations where a straight cable outlet would create additional space requirements.
A suitable bend radius should still be maintained. Excessive bending or mechanical tension can damage the cable or affect connection reliability.
4. Ethernet Data Transmission
The 6AG1901-1BB20-7AA0 supports Industrial Ethernet communication at 10 Mbps and 100 Mbps.
The actual communication speed depends on the connected network devices, cable type, installation quality, and network configuration. All components in the communication path must support the intended transmission rate.
5. Environmental Protection
The SIPLUS version includes conformal coating and is specified for operation from -40°C to +70°C.
This coating provides additional protection for the connector assembly under the environmental conditions specified for the product. It should not be interpreted as making the connector waterproof or suitable for unrestricted exposure to chemicals, liquids, or corrosive substances.
Role in Industrial Control Systems
Industrial Ethernet provides communication links between controllers, remote I/O stations, operator interfaces, engineering equipment, and other networked devices.
The 6AG1901-1BB20-7AA0 serves as a physical connection component within this infrastructure.
PLC Communication
Programmable logic controllers use industrial communication networks to exchange control information with distributed devices and supervisory systems.
A compatible RJ45 connector can provide the physical Ethernet connection between a PLC network interface and the industrial cabling system.
The connector does not determine the communication protocol or controller functionality. These depend on the connected devices and network configuration.
Industrial Ethernet Switch Connections
Industrial Ethernet switches connect multiple devices within an automation network. The 6AG1901-1BB20-7AA0 can be used to terminate compatible industrial cables for connection to suitable RJ45 switch ports.
Correct port configuration, network topology, and cable installation are necessary for stable communication.
HMI and Supervisory Systems
Human-machine interfaces and supervisory computers may exchange operating data with PLCs through Industrial Ethernet.
The connector can form part of the physical communication path between these devices when the cable and network interfaces are compatible.
Distributed Automation Equipment
Modern automation systems often distribute controllers, I/O stations, drives, and monitoring devices across production areas. Industrial Ethernet cabling provides the communication infrastructure connecting these components.
A properly terminated connector helps maintain the physical integrity of the network connection.
