Helmholz Profibus screw connector 700-972-0BA12

Profibus screw terminal connector Helmholz 700-972-0BA12

The Profibus screw terminal connector (art. 700-972-0BA12) is an industrial Helmholz connector designed for Profibus DP networks, featuring quick screw terminals and switchable integrated termination resistors. The metalized housing provides excellent EMC compatibility and shielding against typical industrial electromagnetic interference.

Available in 5 angular configurations (90°, 35° and axial), this connector operates reliably from -25°C to +85°C, ideal for control cabinets in foundries, chemical production lines and harsh environments. The integrated PG interface (select versions) enables direct programming and diagnostics without additional tools.

The screw terminal system ensures robust mechanical connection even with Profibus cables subject to continuous vibration, mechanical movement or tensile stress. Each pin is clearly labeled (A/B for differential signal, GNDE for shield), minimizing wiring errors and facilitating fast maintenance and replacement.

Perfect for Profibus network expansions, Siemens S7-300/400 PLC retrofits and new installations requiring reliable 24/7 fieldbus connectivity. The compact DIN-rail compatible design integrates easily into existing panels without structural modifications.
