6ES7972-0BB52-0XA0 Siemens PROFIBUS Connector 12Mbps

6ES7972-0BB52-0XA0 Siemens SIMATIC DP PROFIBUS Connector with FastConnect Technology

Key Technical Specifications and Design

• Transfer Rate: The connector supports PROFIBUS DP speeds from 9.6 kbit/s up to 12 Mbit/s, ensuring compatibility with both legacy and high-speed modern networks.
• Connection Interfaces: It features two integrated insulation displacement terminals for PROFIBUS cables and one 9-pin sub D connector for network components or terminal equipment.
• PG Socket Integration: A built-in PG connection socket allows for easy programming or diagnostic access without disrupting the existing network node.
• Mechanical Durability: The plastic enclosure includes an integrated terminating resistor, connectable via a slide switch, and a screw locking mechanism for a vibration-proof connection.
• Environmental Tolerance: With an IP20 protection class, it operates reliably in industrial settings, surviving storage and transport temperatures from -40°C to +70°C.

Fast Installation and Network Suitability

• FastConnect Method: This 6ES7972-0BB52-0XA0 utilizes the insulation displacement method (FastConnect) for quick and secure termination of 2-core PB FC installation cables, minimizing assembly errors.
• Silicon-Free Build: The component is silicon-free, making it suitable for use in paint shops and other environments where silicone contamination poses a risk.
• Space-Saving Design: Its compact dimensions (15.8 mm width, 59 mm height, 35.6 mm depth) and 90-degree cable outlet allow for efficient installation in tight control cabinets.
• Strain Relief: Integrated strain relief protects the cable connection from mechanical stress, ensuring long-term network stability.

Frequently Asked Questions (FAQ)

• What is the purpose of the PG socket on the 6ES7972-0BB52-0XA0?
  The PG (Programming Device) socket allows you to connect a programmer or diagnostic tool directly to the network node without removing the main bus connector or interrupting network communication.
• How do I terminate the bus with this Siemens connector?
  The 6ES7972-0BB52-0XA0 includes an integrated terminating resistor. You activate it easily by sliding the visible switch on the housing to the "ON" position when the device is at the end of a segment.
• What cable types work with the FastConnect system?
  This connector works specifically with PROFIBUS FastConnect (FC) standard cables. The insulation displacement contacts are designed for 2-core shielded PROFIBUS cables, ensuring a gas-tight and maintenance-free connection.
• Can this connector withstand high vibration environments?
  Yes, absolutely. The 6ES7972-0BB52-0XA0 features a robust screw-locking mechanism for the sub D connection, ensuring it remains firmly attached to the device even under significant vibration or shock.
