Siemens & Helmholz 700-972-0BA41 | Professional 35° PROFIBUS DP Connector
The 700-972-0BA41 is a premium industrial PROFIBUS connector designed to provide rock-solid network stability for Siemens SIMATIC and compatible automation systems. Manufactured by Helmholz, this high-performance D-sub connector features a 35-degree angled cable outlet, which is essential for modern, high-density control cabinets. It effectively manages the physical connection between PLCs, variable frequency drives, and HMIs while maintaining a compact footprint. Furthermore, the metalized housing provides superior shielding against electromagnetic interference (EMC), ensuring your fieldbus communication remains clear even in electrically noisy environments.
Installing this connector is remarkably straightforward thanks to the time-tested screw terminal design, which offers excellent resistance to industrial vibrations. Because network integrity is critical, the unit includes an integrated, switchable terminating resistor that you can activate with a simple toggle. This feature eliminates the need for external resistors and simplifies the commissioning process for both end-of-line and mid-segment devices. Moreover, the wide operating temperature range ensures that this connector performs reliably in everything from cold storage facilities to high-heat manufacturing floors.

Frequently Asked Questions (FAQ)
Does this connector require a specialized tool for installation?
No, you only need a standard small flat-head screwdriver to secure the wires into the high-quality screw terminals.
Can I use this connector for a PROFIBUS network running at 12 Mbps?
Yes, this connector fully supports all standard PROFIBUS baud rates, including high-speed communication up to 12 Mbps.
What is the benefit of the metalized housing compared to standard plastic?
The metalized surface acts as a Faraday cage, which significantly reduces data errors caused by high-frequency electromagnetic noise.
Is it possible to daisy-chain the bus cable with this module?
Absolutely, the internal design allows for an incoming and outgoing bus cable to be connected simultaneously within the terminal block.
