OMEGA™ sturdy multi-pin connectors provide an efficient means of joining multiwire thermocouple cables. They can be used with multiple OMEGA extension stranded wire for rapid, convenient connections and for dismantling an apparatus without handling individual sensors. When used with MTC Series pins, the connector design utilizes a combination of resilient and rigid dielectric insulators to eliminate internal air voids and prevent the passage of air and moisture into or through the connector. Connectors can withstand ambient temperatures to 200°C (392°F), contributing to an extended connector life.

Important Notes
1. MS Standard Assembly Tools are required to crimp and assemble connectors properly. Order with first purchase.
2. Match pins and sockets to thermocouple alloys–Example: A 12-cavity connector carries 6 thermocouple circuits (pairs) requiring: 6 positive alloy pins or sockets and 6 negative alloy pins or sockets per body.
3. Order bodies in mating pairs. Style MC mates with both style FF and style FC.
4. Backshell cable clamps are recommended with each cord style connector.

Please review Product Spec Sheet pdf for complete product specifications on the MTC Connectors, MTC Precision Contacts, and HPC Economical Contacts

Rated 3 out of 5 by from Could be 5 stars BUT... I like these connectors. They do what they are supposed to. But, trying to figure out what you need is difficult. It would be better if you offered a preconfigured kit with all you need. And, this stuff is too expensive.

Hi, Would it be possible to connect 10 K-type thermocouples to one of the 24 pin models? would this cause any significant difference in the measured temperature from the sensor?

Asked by: MattH99
Hi MattH99 Thank you for the inquiry. The 10 K thermocouples will occupy 20 of the 24 ports. That is fine. Empty ports will not affect the occupied ports. Best regards, OMEGA

Do these connectors come with pins or are they sold separate?

Asked by: dbcarman
Thank you for connecting with Omega. The pins and sockets for the MTC series connectors are sold separate. Each pin and socket is made with thermocouple specific metals to match the wire.
