Benefits of LEMO's Circular Thermocouple Connectors?

 

1.   Thermocouple-Specific Contact Pins:
Our connectors feature contact pins made of the same materials as the thermocouple's compensating wires, ensuring accurate temperature measurement
 and performance.
2.  Modular Design for Flexibility:

Thanks to LEMO's modular design, internal contact pins and insulators are standardized, enabling seamless customization. Transition between plastic and stainless-steel housings or adapt to environmental requirements (waterproof, underwater) with ease. Our connectors can support single or multiple thermocouple pairs within a single housing, simplifying operation. 

3.  Customizable Options:
Need a specialized solution? We offer multi-pole thermocouple connectors and hybrid connectors that combine different types of contacts, tailored to your specific application.

4.  Wide Compatibility:
Supports all major thermocouple types (K, J, E, etc.).
