KMTXL-040U-42 Thermocouple Probes w/Lead Wire & Molded Mini Transition

Supported Applications

The Omega JMTSS series comprises Transition Junction Style Probes with High Temperature Molded Construction designed for temperature measurement. These probes feature a molded transition junction rated to 260°C (500°F) and are available in standard inch dimensions or metric millimeter configurations.

Operating Conditions & Performance

The series meets or exceeds Special Limits of Error (SLE) and EN 60584-2: Tolerance Class 1. The molded transition junction is rated to 260°C (500°F). Standard electrical connections include 40" PTFE-Coated Lead Wires.

Dimensions

• Diameter: 0.040" to 0.125" (Standard) or 1.0 mm to 3.0 mm (Metric)
• Overall Length: 6" or 12" (Standard) or 150 mm or 300 mm (Metric); other lengths available upon consultation with the Sales Department.

Configuration Options

The JMTSS series supports a broad configuration envelope across thermocouple types, sheath materials, junction styles, and dimensional standards. The housing utilizes environmentally friendly cadmium-free liquid crystal polymer.

Select the junction type using the following suffixes in the model number:

• E: Exposed
• G: Grounded
• U: Ungrounded

Key Product Differences

Variants differ by thermocouple type, sheath diameter, insertion length, and material composition. The model number guide follows the format JMTSS-- - . For example, KMTSS-125U-6 denotes a subminiature transition joint probe, Type K, 0.125" O.D. 304 stainless steel sheath, 6" length, ungrounded junction.

Metric variants follow the format KMTSS-M150G-150, indicating a subminiature transition joint probe, Type K, 1.5 mm O.D. stainless steel sheath, 150 mm length, grounded junction. The series also offers Super OMEGACLAD® XL Thermocouple Wire availability.

OMEGACAL Factory CAL is available as an option.
