Import 6es7972-0bb50-0xa0(90 Degree Profibus Connector) — Buy in Bulk from Supplier in China

The 6ES7972-0BB50-0XA0 is a 90-degree angled PROFIBUS DP connector designed for industrial fieldbus applications, manufactured for Siemens-compatible PROFIBUS networks. This connector variant features a right-angle cable exit that conserves cabinet space and reduces bend radius stress on shielded PROFIBUS cables in crowded control enclosures. China Plc Cable Ltd., based in Shenzhen's Longgang District, supplies this component as part of their industrial connectivity portfolio, positioning it for automation engineers managing dense PLC installations where straight connectors interfere with cabinet doors or adjacent modules.

The connector construction centres on a metalised housing with integrated terminating resistor switch, standard for PROFIBUS DP segment termination at 9.6 kbps to 12 Mbps data rates. The 90-degree geometry positions the cable parallel to the device backplane, with typical cable entry accommodating standard PROFIBUS cable diameters of 8.0 to 8.8 mm outer jacket. The integrated programming port, indicated by the "BB" in the Siemens part numbering, allows handheld programming device connection without disconnecting the bus segment, a feature distinguishing this from basic "AB" variants without service interfaces. Pin configuration follows IEC 61158 PROFIBUS standard with shield continuity through the metal housing.

Typical applications include Siemens S7-300 and S7-400 PLC systems, ET200 distributed I/O stations, frequency drives with PROFIBUS interfaces, and third-party devices certified for PROFIBUS DP communication. The 90-degree form factor particularly suits panel-mounted devices where door closure clearance is minimal, or where cable routing follows DIN rail channels. Buyers should confirm with China Plc Cable Ltd. whether this unit carries Siemens original equipment branding or is a functionally compatible third-party equivalent, as this affects warranty coverage and compatibility assurance. The supplier's published response metrics show zero platform activity, suggesting direct outreach to their Shenzhen address for stock confirmation and technical documentation.

China Plc Cable Ltd. is located in Buji Town, Longgang District, Shenzhen, 518112, China, placing the supplier within the Pearl River Delta electronics manufacturing corridor. The company holds a "harbor" trust tier designation with zero percent response rate and zero average response hours recorded on the platform, indicating no documented inquiry history through this channel. Their listed specialisation centres on PLC cables and industrial connectivity components, with this PROFIBUS connector representing a core stock item in their automation accessories range.

The source description references the platform in the product narrative, though the listing attributes supply to China Plc Cable Ltd. No factory certification details, production capacity, employee numbers, revenue data, or client references appear in the available information. The supplier claims ISO and CE certification backing for their products, but no certificate numbers, certifying bodies or scope of certification are provided. Buyers must independently verify company registration, manufacturing or trading status, quality management system credentials, and request sample evaluation before committing to volume orders, particularly given the competitive market for PROFIBUS connectivity components and variable quality among third-party alternatives.
