M12molded

Supported Applications

The Omega M12M Series consists of thermocouple probes featuring molded M12 connectors, designed for temperature measurement in industrial and process environments. These integral connector sensors provide a direct interface for data acquisition systems requiring robust electrical connections.

• Type J (Iron-Constantan) calibrations with 304 Stainless Steel sheaths
• Type K (Chromel-Alumel) calibrations with Inconel 600 sheaths

Operating Conditions & Performance

The M12M Series operates within a connector temperature range of -50 to 90°C (-58 to 194°F). The probes feature an IP67 enclosure rating for the molded connection. Junctions are ungrounded, and the series supports both single and dual element configurations.

• Connector Temperature Range: -50 to 90°C (-58 to 194°F)
• Junction Type: Ungrounded

Configuration Options

The series offers extensive configuration options across sheath materials, diameters, and lengths. Model numbers follow the format M12M<Thermocouple Type><Sheath Material><Diameter Code><Length Code>-U-<Length>. Standard configurations include imperial sizes (inches) and metric sizes (millimeters).

Dimensions and Sheaths

• Type J: 304 Stainless Steel sheath available in 1/8" (3 mm) or 1/4" (6 mm) diameters.
• Type K: Inconel 600 sheath available in 1/8" (3 mm) or 1/4" (6 mm) diameters.

Lengths and Configurations

• Standard Imperial Lengths: 6", 9", 12", 18", 24". Custom lengths are available with additional cost per inch for both sheath materials.
• Metric Lengths: 250 mm, 500 mm, 1000 mm, 1500 mm. Custom metric lengths incur an additional cost per 25mm increment.
• Dual Element: Add "-DUAL" to the model number for dual element configurations at an additional cost.

Electrical Connection

• Molded M12 4-pin connector integrated into the probe housing.
• Extension cables (e.g., M12C-SIL-K-S-F-1.5) are available separately from Omega.

Key Product Differences

Variants within the series differ primarily by thermocouple calibration, sheath material composition, and dimensional specifications. Type J models utilize 304 Stainless Steel (SST), while Type K models use Inconel 600. Diameter codes in model numbers distinguish between imperial sizes (18 for 1/8", 14 for 1/4") and metric sizes (M3 for 3 mm, M6 for 6 mm). The "-U" designation indicates an ungrounded junction.
