Product Overview
The Omega NHX-U-MF is a heavy-duty, standard-size thermocouple connector set consisting of one male plug (NHX-U-M) and one female jack (NHX-U-F). Built with high-purity glazed alumina ceramic bodies, these connectors withstand extreme ambient conditions where conventional molded plastic plugs melt or degrade. The Type U configuration utilizes uncompensated solid copper contacts, making this pair ideal for Type B thermocouple circuits, RTD extension runs, or thermistor instrumentation where matching copper lead wires are required.
Key Features
- Complete matched pair: one standard male plug and one standard female jack
- High-purity glazed white alumina ceramic construction rated for extreme thermal exposure
- Type U uncompensated solid copper-to-copper contacts
- Polarized solid round pin geometry with larger negative pin to prevent mismatching
- Heavy-duty internal wire clamping plates with combination drive screws
- Shell rated from -29°C to 650°C (-20°F to 1200°F)
Applications
- Connecting ultra-high-temperature Type B platinum thermocouples in ceramic kilns or heat-treat furnaces
- Wiring uncompensated 2-wire or 3-wire RTD and thermistor extension leads into control consoles
- High-temperature test bench setups and sensor calibration harnesses in industrial laboratories
- Maker and metalworking furnace temperature monitoring rigs requiring heat-proof connector bodies
Frequently Asked Questions
Can I use these Type U connectors with standard Type K or Type J thermocouples?
Type U connectors feature pure copper contacts rather than matched thermocouple alloys (such as chromel, alumel, iron, or constantan). Using them in the middle of a Type K or J run will introduce junction errors if a temperature gradient exists across the connector terminals.
What wire sizes do the internal terminal clamps accommodate?
The standard NHX series internal clamping plates secure solid or stranded thermocouple and instrument wire up to 14 AWG.
Why choose ceramic over glass-filled nylon connectors?
Glazed ceramic handles continuous service temperatures up to 650°C (1200°F) at the housing, surviving direct radiative heat and furnace proximity that would char or warp standard thermoplastic connectors.
Why buy this connector pair from PartsMine instead of tracking down industrial lots?
You get an exact, genuine Omega ceramic plug and jack pair ready for immediate install without placing a manufacturer backorder or taking on surplus minimums. More pieces cost less each, and the price-break table on this page shows what each quantity costs. Orders ship for $8 flat rate, ship free past $28, and leave our Idaho warehouse the same or next business day.
Glazed alumina shrugs off the kind of direct furnace heat that turns plastic connectors into slag. Bolt it into your high-temp line and read clean numbers without second-guessing the junction.
