Rated 5 out of 5 by from Well Made Bought these to use with Omega Thermocouples. They appear to be well made and easy to connect to thermocouple wiring. Nice that they come with a "locking" wire to keep them connected to the thermocouple. Like the space for labeling the connectors.

I am evaluating SMPW-K-M-ROHS and SMPW-K-F-ROHS for one of my application. Will the TC wire TT-K-24S-SLE (Stranded) and TT-K-24-SLE(Solid) work with these connectors?

Asked by: Senthil
The SMPW-K-M-ROHS and SMPW-K-F-ROHS connectors will work with AWG 24 wire solid core or stranded core. That series of connector with work with wires up to AWG 20 if necessary.

I want to buy SMPW-R/S-F (green R female) The official website color currently looks blue. Want to ask Do I need to write down the color and model clearly when ordering remarks?

Asked by: JYUN
Thank you for connecting with Omega JYUN. The picture does not accurately show the selected calibration type. If a R/S type is ordered, the connector will be green.

Does the female connector portion refer to the wires from the thermal couple or does it mean that the receptor will receive the "chisel point male connectors" shown in the datasheet?

Asked by: preston
Thank you for your inquiry preston. All the thermocouples that come with a miniature male receptor connector will connect to the socket of the female miniature connector.
