Junkosha Multi-Core Cable and Assembly

Ultra-Fine Thermocouple

With the increased use of temperature monitoring catheters, the need for Ultra-Fine Thermocouples is growing.
Junkosha Thermocouple Cables’ structure is increasingly simplified compared to conventional thermistors and can be easily downsized. They can also be used for attaching multi-point thermal sensors to catheters in development.
Few companies can manufacture thermocouples thinner than AWG 38.
Junkosha has successfully commercialized polymer-coated thermocouples smaller than AWG 50.
(Welded assemblies are under development.)

Features

- Great reliability, faster reactivity and improved responsiveness for measurements.
- Excellent thermoelectromotive force
