  • Connettori ultraminiaturizzati triax in versione filettata e a disconnessione rapida
  • Disponibili in versione cablata dritta e a 90° e in versione per PCB
  • Progettati per numerosi cavi triax concentrici e cavi biassiali a bassa perdita

The triax connector line features our ultraminiature NDL connector in both the threaded (NDL-T) and quick disconnect (NDL-Q) versions. The series includes straight and right angle cable and PCB mount connectors and in-series and between series adapters. Cable mount connectors are designed for numerous low-loss twinaxial cables and concentric triaxial cables available in a variety of impedance values. These cables are designed for all types of data-bus and video interconnect systems including MIL-STD-1553B, ARINC 429, 100 Base-T, Ethernet, high speed video hot-link and Fiber Channel data links.
