Siemens SIMATIC DP PROFIBUS DP Connector, Axial Cable Outlet, Up to 12 Mbit/s, 6ES7972-0BB12-0XA0

The Siemens SIMATIC DP PROFIBUS DP Connector (6ES7972-0BB12-0XA0) is a high-performance bus connector designed for reliable data transmission in industrial automation networks. With support for data rates up to 12 Mbit/s, this connector ensures fast and stable communication between PROFIBUS DP devices. Its axial (straight) cable outlet and screw terminal connection simplify installation, while the integrated terminating resistor with switchable ON/OFF function provides flexible network termination. The fully shielded metal housing offers excellent electromagnetic compatibility (EMC) protection, making it suitable for harsh industrial environments.

Advantages

This connector delivers robust performance with a wide operating temperature range (-25 °C to +60 °C) and IP20 degree of protection. The screw terminals allow secure and tool-free wiring of PROFIBUS DP standard cables with diameters from 6.5 mm to 8.0 mm. The integrated bus termination switch eliminates the need for external terminators, reducing installation complexity and cost.
