client Projects
300+ global clients trust sino-conn’ premium service
We encountered phase drift problems when deploying millimeter wave 5G base stations – the original supplier’s cables had a phase difference of ±5° in the 28GHz band. Sino-conn provided a PTFE silver-plated low-loss solution within 48 hours, and controlled the difference within ±1° through 3 iterations of optimization. The first batch of 500 sets has passed the German TÜV certification and is now our exclusive supplier.
“Phase consistency outperforms Rosenberger at 60% cost. Lightning response & free TDR reports sealed the deal!”
Markus Schneider
CTO of TelekomTech GmbH
The fourth axis cabling of the da Vinci surgical robot needs to withstand ethylene oxide sterilization and have a bending radius of less than 15mm. Sino-conn developed a double-shielded PUR cable that passed 10,000 dynamic tests without signal attenuation. What’s even more surprising is that they proactively provided a delivery time that is 30% shorter than the original manufacturer (2 weeks for batch delivery).
“Perfect halogen-free solution! 72hrs from CAD approval to FDA documentation.”
Dr. Sarah Chen
Lead Engineer of SurgiBot Inc.
The extreme desert environment causes oxidation failure of ordinary cable connectors. Sino-conn’s gold-plated stainless steel connector + double-layer EMI shielding solution passed the 55℃/95%RH salt spray test and is equipped with a military quick-plug interface. The first batch of 2,000 sets has zero failures in 18 months on the front line in Kabul.
