Use Case: High-resolution medical imaging device
“We needed ultra-low-loss coaxial assemblies with extremely tight impedance control for our new MRI imaging unit. Our previous supplier couldn’t handle custom pinouts with hybrid connectors. After contacting Shenzhen Sino-Media, I was amazed by how quickly their team responded. Within one day, I received full CAD drawings and impedance testing plans. Samples arrived in 3 days—fully passed our lab test. The quality was impeccable. Their technical know-how, flexibility, and communication were far beyond expectation. We’ve now moved them to our Tier 1 supplier list for all new imaging systems.”
Dr. Markus Reiter
Head of R&D, Munich, Germany
Use Case: 5G base station antenna systems
“We were under a tight rollout schedule for a new set of outdoor 5G antenna arrays. The coaxial cables needed to be weather-resistant, UL and RoHS certified, and built with exact pinouts for field technicians. Sino-Media was the only vendor who offered flexible MOQ and could provide both original-brand connectors and performance-equivalent alternates. Their sample turnaround was just 4 days, and the drawings were spot-on. Even our field installers commented on how easy these cables were to work with.”
