OSTW Series connectors are standard size round pin 2 pole TC connectors. They connect or extend TC wire and cable to thermocouple sensors, temperature instrumentation and process controllers.This popular series of TC connector is available in all thermocouple calibration code colors. The contact washer feature allows the installer to use a straight wire strip. This greatly cuts installation/termination time and eliminates the torque that is normally associated with wire that is looped around a termination screw.

Thermocouple plugs
I would not have bothered to review these, but I have been buying only this brand for years. We like the terminal connection inside, but what I like best is the cord securing segment. It is cut away inside the body so it actually secures the wire when the 2 halves are screwed together. We actually use these for low voltage plugs vs thermocouple connections, using an 18 ga 2 wire sjoow cable. Simple, cheap, rugged.

A better design
In our test chambers TC connectors are exposed to wide temperature swings. With the connector we previously used, the TC wire is wrapped around a screw used for securing the wire. With this design the TC wire and screw become loose over time from the changes in temperature. The design of the Omega connector secures the TC wire between two nonrotating surfaces that are compressed with a screw. We have used the Omega connectors for over two years now and no longer have problems with loose TC connections.

The right stuff!
The plug adapters worked great. My biggest challenge was to find a company that produces the proper size I needed. Omega fill the bill, Thanks

Works great
I bought this a little over a month ago, the male and female plugs work perfectly. Easy to attach wires and have rubber fitting to keep moisture out. Would buy again

Great (Large Body) connectors
I really like these connectors, and use them when instrumenting larger equipment for testing. They are large enough to handle easily when connecting Tc's to them.
