The M8M series of small diameter thermocouple probes with M8 connectors can be used where other sensors can't. Their smaller size allows for measurements in tight spaces, or when you need to have a minimal impact on the thermal environment that you are measuring.

These thermocouple sensors are available in Type J with 304 stainless steel sheaths, or in Type K with Inconel 600 sheaths. The 1/8" diameter version is overmolded in the ANSI color code and is available in 6", 9" and 12" lengths. The 2 mm and 3 mm diameter versions are molded in the IEC color code and is available in 150, 200 and 250 mm lengths.
The connector pin out is as shown in the accompanying figure. To maintain the proper polarity and the use of thermocouple materials from the sensor to your measurement or control instrument, we recommend one of Omega's M8 Thermocouple Extension Cables (listed in the ordering table below).

  • 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 on the 1/8" diameter version, and green nylon on the 2mm and 3mm diameter versions.
  • Note: Molded connectors have a maximum temperature of 90°C.
  • Thermocouple output is per IEC 584-2, Class 2.
  • Fractional sizes are available with 1/8" diameter x 6", 9" or 12" long probes.
  • Metric sizes are available with 2mm or 3mm diameter x 150, 200 or 250mm long probes.
  • Insulation Resistance is 100 megohms at 100VDC for ungrounded sensors.
  • Minimum Bend Radius is three times the outer probe diameter.

  • Connect your M8 thermocouple probe to one of Omega's wide variety of in-stock controllers, data loggers, hand held thermometers, PLCs or other measurement or process control products to complete your measurement or control system.

    Rated 5 out of 5 by from Uniform Probe Diameter These mount in bored-through, 1/8" tube fittings mounted in exhaust system elbows over glass condensers. The 0.124 sheath diameter is a perfect match with common tube fittings.
