MPJ

Supported Applications

The Omega MPJ Series consists of miniature female panel jack connectors designed for compact mounting in temperature measurement systems. These connectors accept OMEGA and industry-standard miniature male thermocouple plugs, providing a secure interface for Type K, T, J, E, R/S, G, C, D, N, and Uncompensated (Type U) applications.

Key application features include:

• Compact Installation: Designed with spring clips for space-constrained panel assemblies.
• Post-Assembly Wiring: Angled terminal screws allow wiring to be completed after the connector is mounted in the panel.
• Type U Compatibility: Type U (Uncompensated) connectors are specifically used with Type B thermocouples (Platinum/6% Rhodium–Platinum/30% Rhodium).

Operating Conditions & Performance

The MPJ Series is constructed from glass-filled nylon, providing durability across a specified ambient temperature range of -29 to 180°C (-20 to 356°F). The connectors are engineered with color-coded shells corresponding to ANSI designations for rapid visual identification.

• Temperature Range: -29 to 180°C (-20 to 356°F).
• Housing Material: Glass-Filled Nylon.
• Note on High Temperatures: Minor discoloration of the connector may occur between 150°C (302°F) and 180°C (356°F); electrical properties are not affected by this change.

Electrical & Mechanical Specifications

• Cutout Required: 8.1 x 16.7 mm (0.32 x 0.66").
• Wire Acceptance: Stranded or solid wire up to 0.8 mm (0.03") Dia. (20 AWG).
• Connector Type: Miniature Female Panel Jack.

Configuration Options

The series offers a comprehensive selection of alloy codes to match specific thermocouple types, each with distinct compensating alloys and shell colors. The model number follows the format MPJ-[Alloy Code]-F.

Accessories & Options

• Extra Mounting Clips: Available as single units (Model MH-MPJ-1) or 5-packs (Model MH-MPJ-5).
• ID Number Labels: Optional labels available in ranges: Model 1-6S, 1-12S, 1-18S, 1-24S, 1-50S, and 1-100S.

Key Product Differences

Variants within the MPJ Series are distinguished primarily by their alloy code designation, which dictates the compensating alloys used in the connector terminals (+/-) and the corresponding ANSI shell color. While most types have unique colors (Yellow for K, Blue for T, Black for J), Types G, C, and D share a Red shell but utilize different internal compensating alloys specific to their respective tungsten-rhenium thermocouple chemistries.

Connectors are supplied with mounting hardware (spring clip). The series includes standard female connectors; variations such as KI or NI suffixes in the SKU list indicate specific inventory configurations for Type K and Type N, respectively, though the primary datasheet defines the core MPJ-[Alloy]-F structure.
