6ES7972-0BA52-0XA0

Product information

The 6ES7972-0BA52-0XA0 is a Siemens PROFIBUS bus connector, RS 485, Fast Connect, without programming port, 90° cable outlet. It connects PROFIBUS stations to the bus cable at transfer rates from 9.6 kbit/s to 12 Mbit/s, with dimensions of 15.8 × 59 × 35.6 mm and a net weight of 36 g.

The Fast Connect designation refers to the insulation displacement termination method: the two PROFIBUS cable cores are pressed into integrated insulation displacement terminals rather than screwed down. That speeds up assembly and removes the need to prepare the conductor ends, which is why Fast Connect connectors are the modern default on new PROFIBUS installations.

Fast Connect versus screw terminals

These two PROFIBUS connector families are not interchangeable in tooling or assembly method. Fast Connect connectors require PROFIBUS FC installation cable and the corresponding stripping tool; screw-terminal connectors such as 6ES7972-0BA42-0XA0 accept conventionally prepared conductors. Choosing the wrong family for the cable on site is a common cause of wasted connectors.

Typical applications

• New PROFIBUS DP wiring where fast assembly with FC cable is preferred
• Connecting drives, remote I/O and controllers to a PROFIBUS DP network
• Bus termination at the segment end using the integrated switchable resistor
• Replacement of damaged connectors on existing Fast Connect installations

Application examples describe typical uses of this product type. Suitability for your own installation must be confirmed against your engineering documentation.

Frequently asked questions

What is Fast Connect?
An insulation displacement termination method — the PROFIBUS cable cores are pressed into integrated terminals instead of being screwed down.

Does this version have a programming port?
No. The 6ES7972-0BB52-0XA0 is the equivalent connector with a programming port.

Which cable does it require?
PROFIBUS FC installation cable with 2 cores, as the terminals are designed for that cable type.

What is the maximum transfer rate?
12 Mbit/s.

What is the price and lead time?
Confirmed individually against current availability and quantity.
