Thermocouple Connectors
Simplify connecting your thermocouple to thermometers and control panels—these connectors give your thermocouple a plug-in connection. To attach them to your thermocouple, first remove the panel on these connectors to expose the terminals. Then insert your thermocouple wire leads, tighten the terminals, and reattach the panel.

Panel-Mount Thermocouple Connection Strips
Create an easy way to plug in multiple thermocouples—these connection strips mount directly into your control panel. With at least two connections on each strip, you can plug in multiple thermocouples to monitor temperature at different points in your process. Each socket is numbered to help identify thermocouples and keep your wires organized. Choose a connection strip with a thermocouple type that matches the type of thermocouple you’re plugging in. You should also make sure the equipment you’re connecting it to is also compatible with the same thermocouple type.
Connection strips for flat-pin mini thermocouple connectors install from the rear of your panel. They snap into place with spring clips.
Connection strips for round-pin thermocouple connectors install from the front of your panel. Just tighten the screws on the front of the strip and T-nuts will hold it in place against your panel.
Add a mounting frame (sold separately) if your panel opening is larger than the cutout dimensions. When using a mounting frame, install your connection strip into the frame before attaching the entire assembly to your panel opening. Use the frame's mounting holes to secure your fasteners.

Conduit-Mount Thermocouple Connection Strips
Already mounted in a conduit box, these connection strips save you the effort of modifying a panel for installation. With six connections on each strip, you can plug in multiple thermocouples to monitor temperature at different points in your process. The sockets are numbered to help you identify thermocouples and keep your wires organized.
To install, remove the connection strip from the conduit box, then pull your wiring through. Attach the box to your conduit, wire up the back of the connection strip, and reattach it to the conduit box. Then just plug your thermocouples into the strip.

Thermocouple Terminal Blocks
Connect thermocouple wires without soldering or splicing. The terminals on these terminal blocks are made from same materials as thermocouples to ensure no signal is lost. Also known as barrier strips, they shield connections from each other to keep them neat and minimize the chance of short circuits. Choose a terminal block that matches your thermocouple type. You should also make sure the equipment you’re connecting it to is also compatible with the same thermocouple type.
For easy wiring, each end is labeled positive or negative. Mount these terminal blocks to a panel or machine using the mounting holes.

Thermocouple Spade Terminals
Easily connect thermocouple wire to screw terminals without completely removing the screw. The open end of these spade terminals allows you to loosen the screw and slide them under the screw’s head. They’re made from the same materials as thermocouples to make sure no signal is lost. You'll need to use two terminals per thermocouple, one for each wire. Make sure to match the material of each individual thermocouple wire to the material of the terminal.
Use a crimper (required but not included) to install your wire in the spade terminal.
