RF Cable and Connector for Physical AI

Low Loss, Low Weight, Robust RF Cable become more and more important for physical AI, where robust communication is critical, such as humanoid robotic systems, Autonomous mobile robots.

As physical AI become more capable, RF Cable and Connector are increasing design to support:
  • Low Loss
  • Low Weight
  • High Vibration
  • Rugged IP67 rated
  • Extreme Temperature Variations
  • Electromagnetic Interferance 
Robust communication provide reliable physical connection on the application of physical AI. Raynool design and manufacture different types of RF Cable and Connector for varies application.
1. MMCX Male Right Angle to SMA Female Waterproof Bulkhead RG178 Cable Assembly
Raynool MMCX Male Straight or Right Angle Cable Assembly is ideal for connection between PCB board and external panel. MMCX connector can withstand higher vibration compared with IPEX, MHF1/MHF4 connector, and compact size can meet the growing demand for miniaturization.
Rugged IP67 rated SMA Bulkhead connector will the attached to external panel, beside SMA, TNC, N-type, BNC, etc., connector can be customized to meet different interface requirement.
RG178 cable provide excellent electrical performance up to 3 GHz, RG178 cable feature flexible, small diameter and light weight, and can attached to large connector which micro coaxial cable can't.
The cable assembly is very low weigh, around 4g/pc.

2. SMA Female Waterproof Bulkhead to MHF1/MHF4 IPEX Connector Micro Coaxial RF1.13mm Cable Assembly
Micro Coaxial RF1.13mm Cable provide excellent light weight, small diameter, excellent EMI performance and it's a very important type of cable assembly.

3. SMA Male to SMA Male, Low Loss RN100 Cable Assembly
For long distance application, Low Loss while maintaning light is very important, Raynool is few of the factory that can manufacture stable and consistant performance Low Loss RN100 cable.
SMA connector is the robust thread type, is one of the most popular connector interface for physical AI, besides SMA, other connectors are also available, for example, 1.0/2.3 Connector is a compact, push pull RF connector for high density application.

4. SMA Male to SMA Male, RG223 Cable Assembly
Besides popular Low Loss 195, Low Loss 200, Low Loss 240 Cable Assembly, Raynool also manufacture cable assembly which are not easy to find on the market, RG223 feature solid PE dielectric and can withstand higher power than Foam PE Dielectric(Low Loss series cable).

Why SMA Connector?
SMA Connector is widely used and one of the most popular interface in IoT application, the SMA interface can save unnecessary adaptor. Small size make the physical connection low profile, robust thread connection is more suitable for vibration circumstance, compared with MCX, Fakra, SMB push-pull connection.

Stainless Steel RF Connector for Robust Communication.

Raynool can customize Stainless Steel SS303, SS304, SS316 SMA, N type Connector for robust connection, which can withstand higer vibration and severe environment than brass body.

Physical AI is more than a physical robot, and the boundaries are expanding every day, Raynool dedicate to the best fit RF cable assembly and RF connector for our customer's requirement. Contact Raynool sales@raynool.com today if you need any support on your physical AI project.
