uxcell5 Pcs Yellow Plastic Case SMPW-K-M K Type Thermocouple Wire Connector

I bought a package of 5 thermocouples a few months ago and had intermittent problems appear due to poor internal connections within the thermocouple connector. I found that the thermocouple wires had been crimped to the connector blades, but poorly. one of the two wires was not securely fastened within the crimp connection. These new connectors use threaded screw connections and work well. To ensure a good grip to the thermocouple wire pair sleeve, I added a short shrink tubing sleeve where the wires entered the connector housing. No problems sense.

Good product

Good product, but could be a little stronger. For $5.13 for a 5 pack it certainly does it's job. I've been using one for over 3 months and it's done the job. Although it has proven itself I just wish I had more confidence in it. It have thought about wrapping electrical tape around it to keep it sealed because it just doesn't exude ruggedness. Should it ever break, I'll just use one of the other 4. Since it does the job, and it's inexpensive, it gets a 4. It would have to be a little more rugged for me to give it a 5.

So often screws are weak and strip out. I was able to tighten the two contact screws down very tightly and they held fast. I'm happy with the quality.

These plugs just saved me a lot of money pretty hard to install took some time acuracey is ok. We'll worth buying free shipping took fora long time but hay it was free came from china

It works as it should. It came packaged very good. I had no issues with it at all. It works like a champion!

Works excellent for making thermocouples switchable. I have a TC attached to each of my bullet molds and it is very easy to switch them.

THIS is NOT a REAL K-type compliant connector.It is NOT made of Alumel and Chromel which are the metals used in a K-type thermocouple wire. A REAL connector IS made of CH and AL.Typically, the plugs have AL and CH stamped on the exposed portion of the blades. The jacks will say CH and AL also. On jacks it is printed on the yellow plastic somewhere along with a “+” and a “-” for polarity.AL is MAGNETIC, CH is NOT. If both of your connector's metal parts ARE magnetic OR both are NOT, THAT is another way to tell your connector is NOT a REAL K connector.If you use this you absolutely WILL introduce error into your readings because the junctions created by attaching the connectors to the wires and plug will turn this into a thermocouple as well since you will have alumel connected to a DIFFERENT metal, and chromel connected to a DIFFERENT metal... whatever metal IT is.!!! Real cute in the ad. They CALL it a K-type yet DON'T tell you it isn't made of the correct metals and therefore NOT compliant!NEVER, EVER, EVER buy this if you want accurate readings from a actual thermocouple.EXAMPLES:Scenario A: TC Chromel and Alumel--->Fake Plug--->measuring equipment.In this configuration, The TC, as well as the connections IN the PLUG are also t-couple junctions. The connection IN THE jack is where it SHOULD be.Scenario B:TC Chromel and Alumel--->Fake Plug--->Fake Jack--->K-type wire--->Fake Plug---> measuring equipment.In this configuration which uses a extension cable, The TC, the connections IN the PLUG AND again IN the jack of the first plug/jack set AND IN the second plug are ALL t-couple junctions! Heating or cooling any of them WILL change your reading!IF they all were REAL plugs and jacks, the ONLY places affected by temperature would be the t-couple weld (Sensor) and the JACK of the test equipment and NOTHING else. Cute how they conveniently omit this fact and still call them K-type no?
