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 Audio Equipment Connectors
These connectors mount to panels of any thickness, as long as you drill a mounting hole first.
Normally open connectors turn equipment on when a device is plugged in. Normally closed connectors turn equipment off when a device is plugged in.
Protect connectors when not in use by covering them with caps (sold separately). Caps are tethered, so you can open them in any direction for access from any angle.

Panel-Mount Audio Equipment Adapters

Mini Splitters
Simplify wiring and reduce the number of cords in your automation setup. These splitters create a branch off a main cord or connect multiple devices with a mini connection to a single port in a junction box or I/O module. A threaded housing securely mates with other mini connectors to keep out contaminants and won’t come loose from shaking or vibration. They have a standard pole layout and housing thread size to reduce the chance you’ll mis-mate connectors.
When mated, these connectors meet IP68 and NEMA 6P for protection against dust, submersion, washdowns, and weather.
Caps protect connectors and maintain their IP and NEMA ratings when not in use.
Thread adapters connect plugs and sockets that both have internal threads.
