Frequently Asked Questions

What is the difference between a thermocouple connector and a standard electrical connector?

Thermocouple connectors are specifically designed to maintain the thermoelectric properties of the junction, with materials and construction that minimize thermal EMF errors and ensure proper polarity matching for accurate temperature measurement.

Can different thermocouple types use the same connector?

No, different thermocouple types (J, K, T, E, etc.) require specific connectors with different color coding and pin configurations to prevent mismatching and measurement errors.

How do I select the right thermocouple connector for high-temperature applications?

Consider the maximum operating temperature, environmental conditions (moisture, chemicals), required IP rating, material compatibility with thermocouple type, and compliance with relevant industry standards.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
