Thermocouple connector optimal for temperature measurement instruments.

This is a multi-pole connector used for connecting compensation leads, with contacts made from the same metal as thermocouple wires. As a result, measurement errors due to dissimilar metals are minimized. The contacts are available in five types: copper, iron, constantan, alumel, and chromel, and they can be arranged in a unique configuration using crimping. The connector itself has a temperature range of -55°C to 200°C, so during high-temperature measurements, the connector body should be kept away from the measurement point, allowing temperature measurement through the thermocouple contacts. ◎ For more detailed information, please refer to the catalog or contact us directly.
