These thermocouple probes provide a quick and convenient method for measuring temperature in your process. They can be used as-is, mounted into your process using one of Omega's line of Compression Fittings, or used in a thermowell by using one of our Spring Loaded Fittings.

The M12 Series thermocouple probes are available as Type K thermocouples with Inconel 600 sheaths, or as Type J thermocouples with 304 Stainless Steel sheaths. Standard probe sizes include 1/4" and 1/8" diameters with lengths of 6", 9", 12", 18" and 24", and metric sizes in 3mm and 6mm diameters with lengths of 250, 500, 750, 1000 and 1500mm. These thermocouple sensors can also be requested in other lengths as needed.
The connectors on these sensors are overmolded with the IEC standard color code on the metric sizes and the ANSI standard color code on the fractional sizes. The connector pinout is as shown in the accompanying figure.

To connect this sensor to your measurement or control instrument, we recommend using one of Omega's M12 Extension Cables (listed in the ordering table below). Besides these extension cables, Omega offers a selection of specially assembled extension cables in a variety of cable materials with optional stainless steel braid or hose for improved mechanical protection, and a wide selection of instrument connections.

  • Type J Thermocouples have a 304 SST sheath with a temperature range of -40 to 600°C, with the connector overmolded in black nylon.
  • Type K Thermocouples have an Inconel 600 sheath with a temperature range of -40 to 1150°C, with the connector overmolded in yellow nylon for fractional sizes and green nylon for metric sizes.
  • Note: Molded Connectors have a maximum temperature of 90°C
  • Thermocouple Output is per IEC 584-2, Class 2.
  • Fractional sizes are 1/4 and 1/8 inch diameters in lengths of 6, 9, 12, 18 and 24 inches.
  • Metric sizes are 6mm and 3mm diameters in lengths of 250, 500, 700, 1000 and 1500mm.
  • Insulation Resistance is 100 megohms minimum at 100 VDC for ungrounded sensors.
  • Minimum Bend Radius is three times the outer diameter of the sensor.

  • Connect your M12 thermocouple probe to one of Omega's wide variety on In-Stock controllers, data loggers, hand held thermometers, PLCs or other measurement & control products to complete your measurement or control system.

    why are these only rated down to 0 C

    Asked by: mark3234324
    The probes will work at temperatures below 0C (32F). It is the accuracy for the probe is only stated from 0C (32F) and above.

    Is the probe bendable?

    Asked by: Solvus
    These Thermocouple probes are bendable using a twice the diameter as the bend radius.
