Siemens 6ES7902-2AG00-0AA0 Cable

This communication cable connects SIMATIC S7 or M7 programmable controllers to programming devices. The Siemens 6ES7902-2AG00-0AA0 enables reliable data transfer between PLCs and engineering workstations. It supports the MPI (Multi-Point Interface) and PROFIBUS DP protocols for versatile connectivity. The cable features robust shielding to protect signals from electrical noise interference. Its pre-assembled connectors simplify installation and reduce wiring errors.

Mechanical Dimensions and Construction Quality

The cable measures 5 meters in total length for flexible installation options. Its durable PVC jacket resists oil, abrasion, and mechanical stress in industrial environments. Weighing approximately 0.45 kg, the 6ES7902-2AG00-0AA0 offers manageable handling during installation. The cable uses twisted-pair conductors for optimal signal integrity and noise rejection. This construction minimises data errors even in electrically noisy factory settings.

Interface and Connectivity Features

A 9‑pin D‑sub female connector attaches to the programming device or PG. The other end features a 9‑pin D‑sub male connector for the PLC interface. Both connectors have locking screws for secure mating and vibration resistance. The cable follows standard MPI/PROFIBUS pin assignments for plug‑and‑play compatibility. A green LED on the programming device connector indicates active communication.

Electrical and Transmission Characteristics

The Siemens 6ES7902-2AG00-0AA0 supports data rates from 9.6 kbps to 12 Mbps seamlessly. Its characteristic impedance of 150 Ω matches PROFIBUS cable specifications precisely. The twisted‑pair conductors minimise crosstalk and common‑mode noise interference. Braided copper shielding provides 85% optical coverage for excellent EMC performance. The cable maintains signal integrity over the full 5‑meter length without repeaters.

Internal Construction and Component Details

Two stranded copper conductors form the twisted pair for differential signal transmission. A drain wire runs alongside the pair for easy shield termination at both ends. The cable core includes a foil wrap beneath the braided shield for added protection. Precision moulded connectors ensure reliable pin contact and mechanical durability. The connectors incorporate strain relief boots to protect the cable entry points.

Environmental Performance and Certifications

This communication cable operates reliably from -40 °C to +70 °C in harsh conditions. Its PVC jacket resists oils, greases, and common industrial chemicals effectively. The 6ES7902-2AG00-0AA0 complies with IEC 61158, UL, and CSA standards. These certifications guarantee reliable performance in global automation installations.
