Discover RADSOK® Technology from Amphenol Industrial—engineered for high-current, low-resistance connections across EV, solar, heavy equipment, and power systems. Learn how our technology improves efficiency and durability.
RADSOK® technology is Amphenol Industrial’s signature contact innovation engineered for superior current-carrying performance. Designed to support the electrification of modern systems, RADSOK® delivers low contact resistance, minimal insertion force, and exceptional durability in rugged environments—making it a trusted choice across transportation, industrial automation, renewable energy, and datacom.
What is RADSOK® Technology?
RADSOK® (RADial SOcKet) is a proprietary contact system featuring a hyperbolic grid of twisted, high-conductivity alloy wires. This design increases the contact surface area between mating pins and sockets, enabling up to 50% more current-carrying capacity than traditional contacts of the same diameter. The result is efficient power transfer, reduced heat generation, and extended connector life. For even greater performance in harsh environments, Amphenol Industrial offers the next-generation RADSOK® Enduro-RX™ contact technology, which delivers superior shock, vibration, and mating-cycle durability—learn more in the product brief.
Key Advantages of RADSOK® Contacts
- High Current Capacity: Supports up to 1,200 A depending on the contact size
- Low Insertion/Extraction Force: Eases assembly while maintaining a secure connection
- Low Contact Resistance: Improves power efficiency and reduces system losses
- High Mating Cycles: Exceeds 1,000 mating cycles without degradation
- Rugged Reliability: Maintains electrical integrity in high-vibration or harsh environments
