Neutrik - NBNC75BDD6 - BNC Rear Twist 75 ohm Connector

Neutrik NBNC75BDD6 rearTWIST HD BNC 75Ω Connector

The Neutrik NBNC75BDD6 is a professional 75Ω rearTWIST HD BNC male cable connector engineered for high-definition broadcast, digital video, and professional AV applications. Designed with Neutrik's patented rearTWIST® locking system, this connector provides effortless connection and disconnection in high-density patch panels, recessed bulkheads, and tightly packed equipment racks, where conventional BNC connectors can be difficult to access.

Featuring a true 75Ω impedance design, the NBNC75BDD6 delivers the precision required for SDI, HD-SDI, 3G-SDI, HDTV, and other professional digital video formats. Precision Swiss-machined brass components, a gold-plated centre contact, and PTFE insulation ensure excellent electrical performance, low signal loss, and outstanding long-term reliability.

The connector incorporates Neutrik's advanced shield and jacket crimp system, eliminating exposed grounding braid while providing exceptional cable retention and mechanical strength. Rated for more than 1,000 mating cycles, it is designed to withstand the demanding conditions of broadcast studios, touring productions, rental inventories, and permanent AV installations.

The NBNC75BDD6 is specifically designed for smaller diameter professional broadcast coaxial cables, including Belden 1855A, Clark Wire CD7523-7, and CommScope 7538.
