The Siemens 6ES7972-0BB42-0XA0 provides a reliable connection solution for PROFIBUS DP networks. This bus connector features a 35-degree inclined cable outlet, which saves space in tight control cabinets. It supports transmission speeds from 9.6 kbps up to 12 Mbps, making it suitable for a wide range of automation applications. Additionally, the connector includes an integrated terminating resistor with an isolating function, accessible via a simple slide switch.
The PROFIBUS connector offers screw-type terminals for secure cable termination. It accommodates two PROFIBUS cable connections and provides one 9-pin Sub-D connector for network components or terminal equipment. Furthermore, this model includes a PG programming port, allowing engineers to connect programming devices without disconnecting the bus cable. The connector's design ensures a stable and vibration-resistant connection in industrial environments.
This bus connector supports the full PROFIBUS DP speed range, operating at any rate between 9.6 kbit/s and 12 Mbit/s. It automatically adapts to the network's baud rate, requiring no manual configuration. Consequently, users can deploy the 6ES7972-0BB42-0XA0 across various network speeds without concern for compatibility issues.
The integrated terminating resistor features a slide switch for easy activation or deactivation. When engaged, the resistor combination provides proper bus termination at the end of a PROFIBUS segment. Its isolating function disconnects the termination from the network when not required, preventing signal reflection problems. This design simplifies network commissioning and reconfiguration tasks significantly.
The SIMATIC DP connector measures 15.8 mm in width, 54 mm in height, and 39.5 mm in depth. Its compact footprint makes it ideal for high-density panel installations. The plastic enclosure offers reliable insulation and protection, while the screw locking mechanism ensures secure mating with the device port. It weighs only 34 grams, placing minimal strain on connected components.
This connector operates reliably across a broad temperature spectrum from -25 °C to +60 °C. For storage and transportation, it withstands temperatures between -40 °C and +70 °C. With an IP20 protection rating, it provides adequate defense against solid objects larger than 12.5 mm. Moreover, the connector is silicon-free, making it suitable for applications with strict material compatibility requirements.
The 35-degree inclined cable outlet distinguishes this connector from straight versions. This angled design reduces bending stress on the cable and minimizes the required clearance depth. As a result, it fits comfortably in shallow cabinets where straight connectors would not work.
Installing the 6ES7972-0BB42-0XA0 follows a straightforward process. First, strip the PROFIBUS cable and attach the wires to the screw terminals (A and B). Next, secure the cable using the integrated strain relief to prevent mechanical stress on the terminals. Then, insert the connector into the device's PROFIBUS port and tighten the locking screws. Finally, set the terminating resistor slide switch to the ON position if this connector sits at the end of a bus segment.
For proper network operation, terminate both ends of each PROFIBUS segment. Place the PROFIBUS bus connector with its terminator ON at the first and last stations only. Leave the terminating resistor OFF for all intermediate stations. Additionally, avoid exceeding the maximum segment length of 100 meters at 12 Mbps or 1,200 meters at 93.75 kbps.
