Siemens 6ES7972-0BB12-0XA0

Choose Rayon Automation's Siemens 6ES7972-0BB12-0XA0, which integrates the PG programming interface. This allows engineers to directly access the programming device or HMI terminal for debugging without interrupting the existing PROFIBUS communication. The internal built-in switch-type terminal matching resistor enables on-site personnel to easily complete impedance matching at the end of the bus by simply sliding the switch, effectively avoiding signal reflection and transmission interference. Choosing us as your supplier, we ensure that your automated production line can operate continuously, stably and efficiently by providing sufficient in-stock inventory, rigorous outbound inspection and a complete international logistics channel.

Parameters

Product Performance Metrics

The Siemens 6ES7972-0BB12-0XA0 is capable of supporting a maximum data transmission rate of 12 Mbit/s, with extremely low signal delay, and complies with the PROFIBUS IEC 61158/EN 50170 international standards. The terminal resistance switching mechanism of the connector features high reliability. When connected, it automatically disconnects the downstream bus segment. The overall protection level reaches IP20 and it can operate stably in industrial-grade temperature environments ranging from -25°C to +60°C.

What are the main differences between Siemens 6ES7972-0BB12-0XA0 and 6ES7972-0BA12-0XA0?

Both have exactly the same dimensions and outlet angles, both being 90 degrees. 0BB12 has a PG programming socket, allowing the insertion of programming cables or connection of text displays without unplugging the bus connector; while 0BA12 does not have this PG expansion port.

Core feature

Unlike ordinary bus connectors, Siemens 6ES7972-0BB12-0XA0 adopts a highly durable shielded plastic housing to resist strong electromagnetic interference (EMI) in the factory environment. The terminal connectors have undergone rigorous anti-vibration design, and are less likely to cause screw loosening or reduce contact problems when used near high-frequency vibrating equipment such as press machines and vibrating feeders.

Delivery, unpacking and packaging

Packaging standard: Each connector retains the original anti-static sealed bag and original box packaging from Siemens.

Logistics timeliness: We have deep cooperation with DHL, FedEx, UPS and many international freight forwarders. After receiving the order, the goods will be dispatched from the warehouse within 24 to 48 hours.

FAQ

Under what circumstances does the terminal resistance switch need to be pushed to the "ON" position?

At the beginning and end of a PROFIBUS bus segment, the terminal resistance switch on the connector must be pushed to the "ON" position.

If we encounter technical problems during installation or communication establishment, can you provide assistance?

Yes. Our technical support engineers can provide remote troubleshooting guidance, covering aspects such as wiring methods, grounding of the shielding layer, and whether the terminal resistance settings are correct.

How many days does it usually take from placing an order to receiving the goods?

For orders with available stock, we dispatch them within 24 hours after confirming the payment. If the order requires a specific model, we first communicate to determine the confirmation time. We use international courier services such as DHL/FedEx, or we can also use the transportation method specified by the customer.
