Product Overview
When signal interruptions and loose connections disrupt PROFIBUS networks, the Siemens 6ES7972-0BA52-0XA0 SIMATIC DP Connection Plug delivers a secure, high-performance solution. This robust connector uses insulation displacement technology and a 90° cable outlet to maintain reliable data transfer in demanding industrial environments. As part of the RS485 bus connector family, the 6ES7972-0BA52-0XA0 ensures consistent communication between PROFIBUS stations and the bus cable.
Technical Specifications Breakdown
The Siemens 6ES7972-0BA52-0XA0 supports transfer rates from 9.6 kbit/s up to 12 Mbit/s with PROFIBUS DP, matching the speed requirements of modern automation systems. It features two electrical connections for PROFIBUS cables using integrated insulation displacement terminals and one connection for network components via a 9-pin sub D connector. The integrated terminating resistor is activated by a slide switch, simplifying network termination. Mechanical dimensions are compact: 15.8 mm width, 59 mm height, and 35.6 mm depth, with a net weight of only 36 g. The enclosure is made of plastic with a screwed joint locking mechanism. It operates reliably in temperatures from -25 °C to +60 °C and withstands storage and transport from -40 °C to +70 °C. The product carries IP20 protection and is silicone-free, with RoHS and UL approvals.
Real-World Applications
The Siemens 6ES7972-0BA52-0XA0 is ideal for manufacturing lines where PROFIBUS DP networks control drives, sensors, and actuators. Its 90° cable outlet simplifies installation in tight cabinets, reducing cable strain and preventing disconnections. In process automation, the connector’s FastConnect technology allows quick, reliable wiring without special tools, minimizing downtime. By eliminating common failure points like loose terminal screws and poor contact, the 6ES7972-0BA52-0XA0 improves overall network reliability.
Installation & Setup Guidance
To install the Siemens 6ES7972-0BA52-0XA0, first strip the PROFIBUS cable and insert the wires into the insulation displacement terminals. Ensure the cable is oriented at a 90° angle for proper fit. Tighten the screwed joint locking mechanism to secure the plug. Use the slide switch to enable the terminating resistor if the device is at the end of the bus segment. No PG socket is included, so plan for direct connection to the bus network. Always verify the transfer rate settings match your PROFIBUS DP configuration.
Selection Guide & Purchasing Advice
Before purchasing the Siemens 6ES7972-0BA52-0XA0, confirm your PROFIBUS cable type and transfer speed requirements. This connector is suitable for 2-core PB FC installation cables and supports up to 12 Mbit/s. For systems requiring a PG programming socket, consider alternative models. PLC Source PRO (ubest101) stocks genuine Siemens modules and connectors, ensuring compatibility and warranty support. Order the 6ES7972-0BA52-0XA0 to replace aging connectors or as a standard spare for new installations.
