Cryogenic Wiring

01

High-Density Cryogenic Wiring

Each KF40 feedthrough supports up to four independent 24-core twisted-pair cables, providing a total of 96 signal lines within a single cryostat port. This high-density architecture reduces occupied flange space and supports large-scale quantum computing platforms.

Material Options

02

Phosphor Bronze Twisted Pair：
Optimized Thermal Isolation

Phosphor bronze provides an excellent balance between electrical conductivity and low thermal conductivity, making it well suited for cryogenic bias wiring where minimizing heat leakage is critical.



Superconducting NbTi Twisted Pair：
Ultra-Low Resistance Signal Delivery

Below its superconducting transition temperature, NbTi conductors provide extremely low electrical resistance while maintaining excellent thermal isolation, making them ideal for ultra-sensitive cryogenic applications requiring minimal voltage drop and stable bias delivery.

Fully Customizable Connectivity

03
