uxcell® 2 Pcs Yellow SMPW-K-M/F K Type Thermocouple Wire Connector

Don't buy these unless you like being really frustrated! Although mechanically OK, you can't use these connector pairs as shipped... The two screws that hold down the thermocouple wires are not included on the female sockets (not even on the product photo, which I noticed later). How lame! They are, however, included on the male plug. Had I noticed the screws were not included on the female end, I would have never bought them. Now I have to hunt for some wierd-threaded tiny screws.

The item delivered, while similar in function wasn't the one shown in the main photo, it is the one that has thin flat connectors and is shown in a too small "detail" photo and not one with the round ones. Also, the screws for the wire connections on one side are missing - the part was cheap so I didn't bother returning it, but I wouldn't buy it again.

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?AND they are missing screws for the jack - L A M E
