When it comes to test and measurement, the SUCOFLEX 500 assemblies guarantee the highest level of satisfaction. Thanks to their unique cable and connector design, they deliver the best phase and amplitude stability versus flexure, movement, temperature and tensile stress, in combination with outstanding return and insertion loss up to 70 GHz. 

Due to the rotary swaged low-loss inner conductor and the rugged construction, all SUCOFLEX 500S assemblies withstand more than 100,000 flexures without degradation of performance and therefore have a very long life-time. HUBER+SUHNER supplies all SUCOFLEX 500 standard length products within five working days and customised lengths are available within ten working days worldwide.

  • Applicable in frequencies up to 70GHz
  • Excellent insertion and return loss
  • Outstanding phase and amplitude stability with flexure and movement
  • Very long service life (>100.000 flex cycles)
  • Variety of interface options available
