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.

Is it OK to use Loctite on screws that hold down thermocouple wires?

Asked by: Pharma
Hi Pharma, Thank you for the inquiry. I would not recommend. Coating may have some electrically insulative effect. Best regards OMEGA

Is it possible to buy just replacement silicone grommets for this part? It's listed on the datasheet as follows: Silicone Wire Grommet SR-SMP

Asked by: Stingray360

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.

Why the narrow temperature range for the K of -29C to 180C? Can these be used outside this range with maybe somewhat reduced accuracy? if so how bad is it? or does it not work well enough to be useful?

Asked by: bill4711
Thank you for your inquiry. This an Operating Temperature Range. The body of the connector is rated for -29°C to 180°C.
