Neutrik NBNC75BUU11 rearTWIST BNC Male Crimp Connector for 75 Ohm Coaxial Cables

Professional video and broadcast installations demand reliable, high-frequency connections that maintain signal integrity. The Neutrik NBNC75BUU11 is a straight BNC male crimp connector engineered for 75 Ohm coaxial cables, ensuring precise impedance matching and minimal return loss in HD-SDI and similar digital video applications. Its rearTWIST bayonet locking mechanism provides secure mating and quick release, even in dense patch panels.

Who is it for

This connector is ideal for broadcast engineers, AV technicians, and system integrators who need to terminate cables such as Belden 1855A, 1505A, or 1694A. It suits studio wiring, OB vans, and permanent installations where dependable, repeated connections are critical.
