Single-Channel Rotary Joints

SPINNER's contacting single-channel rotary joints stand out for their extremely large bandwidth up to 67 GHz. Excellent VSWR and insertion loss values with very little variation in rotation throughout the complete frequency range makes these rotary joints suitable for a broad range of applications in measurement technology. The typical lifetime of rotary joints is about 10 million revolutions. The use of rotary joints can help to significantly extend the lifetime of other measurement components. A SPINNER single-channel rotary joint is connected between the test port of the measuring device (e.g.: vector network analyzer) and the cable. This relieves the expensive measurement cable of torsional strain and prolongs its useful life time.

SPINNER precision single-channel rotary joints are available with 3.5 mm, N and 7-16 connector standards and for frequencies up to 67 GHz.


If you can’t find your single-channel rotary joint according to your specifications online, please contact our sales team with the specification needed per email or select one of the displayed products for a Quote Request and add your special requirements in the comment field of the form before submitting.
