Reliable Connection Solution
The 6ES5731-1CB00 provides a durable plug-in connection cable for Siemens SIMATIC S5 automation systems. This cable links the central controller to remote I/O stations and peripheral devices. It features a 25-pin D-sub connector on the CPU end. A 15-pin D-sub connector interfaces with the remote I/O module. Consequently, it ensures reliable data transmission over moderate distances.

Mechanical Design and Durability
The 6ES5731-1CB00 incorporates robust overmolded strain relief boots on both connector ends. This design effectively prevents conductor fatigue from repeated bending cycles during maintenance. Gold-plated contacts ensure reliable signal integrity and resist corrosion in industrial environments. Additionally, dual-layer shielding rejects electromagnetic interference from variable frequency drives and other sources.
Application and Integration
This plug-in cable connects S5 CPUs to remote I/O racks and distributed I/O stations. The 3-meter length provides sufficient reach between the controller and nearby devices. Users should avoid exceeding the total bus length of 100 meters when daisy-chaining.
