A ruggedized connector has an extra-large thread body to stabilize the test cable when connecting it to the test port of an RF measurement device.
It surrounds and protects the sensitive coaxial connector that transmits RF signals by minimizing the potentially damaging axial and radial forces that the port is subjected to. These connectors also let you directly attach an appropriate precision coaxial plug with standard thread.
Another commonly used expression is “NMD plug connector”. NMD stands for “network measurement division”, a reference to the original Hewlett Packard department (now called Keysight) that used to make network analyzers. An additional ball bearing in the coupling nut of the SPINNER ruggedized test port adapter prevents direct friction of the outer conductor.
This prevents metal dust from being created where the coupling nut and outer conductor meet and stops undesirable twisting of the outer conductor when tightening the coupling nut in some pairings. Rotational stability is consistently ensured, and no dust or other debris is constantly ground into the opposite connector. The advantages of this new precision adapter from SPINNER are as clear as day!
SPINNER Ruggedized Test Port Adapters
Ruggedized versions are available for combining with all popular standard coaxial connectors.
The outer conductor can’t be accidentally twisted.
The outer conductor or coupling nut can’t abrade, preventing metal dust from being ground into the contact surfaces.
Ceramic ball bearings reduce the test port adapter’s thermal conductivity.
Excellent phase and amplitude stability.
The robust design reduces externally applied forces.
Ruggedized test port adapter from 50 to 75 ohms available.
