Thermocouple Connectors - Thermocouple Plugs, Thermocouple Jacks and RTD Connectors - manufactured by TC

Miniature Thermocouple Connectors - manufactured by TC

These flat pin miniature connectors are ideal for connecting thermocouple sensors and extension or compensating wire to each other and to instrumentation. The pins are polarised to avoid incorrect connection and the connector body is additionally marked for polarity. They are rated for use up to 425°F, 660°F or 1200°F (220°C, 350°C or 650°C).

Colour coded to ANSI standards and available as a plug, jack or panel jack as well as 3-pin and duplex versions versions. We also offer a range of matching anodised aluminium and stainless steel miniature connector panels. Weatherproof neoprene boots for added protection in moist environments and wire clamps are also available along with a wide range of accessories.

When to use a Thermocouple Connector

Although the simplest of thermocouples end in bare wires (as found in many laboratory and industrial/research applications, for example), there are many other applications where a connector is usually desirable to make life easier.

We manufacture miniature and standard size thermocouple connectors which are available for use with all common thermocouple types and for use with copper conductors in applications involving resistance thermometers. For thermocouple applications, thermocouple grade alloys are incorporated in the contact parts of the connector. This avoids the generation of unwanted EMFs if the connector is not held at uniform temperature.

The connector is usually used to connect the thermocouple sensor to thermocouple or extension cables, then on to the reference junction and the instrumentation concerned. The connectors allow for rapid fitting or exchange of sensors without sacrificing thermocouple conductor uniformity. Plug and jacks are designed so that their installation can be made simply and securely, with designed-in locking mechanisms. Plugs and jacks are polarized by size and are usually marked for negative and positive polarity. Although there is no standard as such, connectors are generally pin compatible with devices from several manufacturers.

In general, although connector bodies for thermocouples are colour coded in accordance with the thermocouple standards (ANSI MC96.1), bodies of the higher temperature rated devices are coloured brown or white (depending on maximum temperature), irrespective of their thermocouple code. Bodies are then marked with their thermocouple type letter only.

Accessories include connector panels (standard and miniature), for stacking of jacks in multiple thermocouple applications, and barrier terminal strips. The latter have lugs marked to identify both alloy and polarity, and are available for most of the common standard types of thermocouple as well as copper wires for resistance thermometers. We also have a range of other connectors for thermocouples including barrier terminal blocks.
