Miniature Thermocouple (TC) Connectors are an essential accessory for users of thermocouple feedthroughs. They provide a secure and stable connection between the thermocouple inside the vacuum chamber and external instrumentation on the air side.

MDC offers Miniature Thermocouple Connectors engineered for both air-side and vacuum-side service, ensuring accurate transfer of milli-volt (mV) and milli-amp (mA) thermoelectric signals under demanding conditions.

Voltage/Current Rating: milli-volts (mV), milli-amps (mA).
Connector Temperature Rating: up to 125°C.
Weldable Vacuum Components: withstand up to 450°C.
Maximum Bakeout Temperature: Conflat CF flanges up to 450°C, Kwik-Flange™ up to 150°C.
Thermocouple Compatibility: TC types C, E, J, K are standard; Type N available upon request.
Connector Type: Miniature (compact, industry-standard).

Industry Applications

Miniature Thermocouple Connectors are widely used in temperature measurement and monitoring across vacuum and high-temperature systems. They are ideal for semiconductor fabrication, thin-film deposition, vacuum furnaces, plasma processes, metallurgy, electron beam systems, and research laboratories. With their high bakeout resistance, reliability, and compatibility with multiple thermocouple types, these connectors ensure stable temperature readings and long-term durability in demanding industrial and scientific environments.
