Connector Head Types

Micro Connector Heads:

For Mounting directly on thermocouple sheath stem by compression fitting. Large head terminal screws facilitate tight connections. Bodies are molded of high performance thermoset compounds (will not melt) for high strength and dependability. The color coded micro heads will withstand ambient temperatures to 400°F (205°C) continuous 500°F (260°C) intermittent. High-Temperature micro heads (ALL Hi-Temp micro heads are color coded red) will withstand ambient temperatures to 800°F (425°C) continuous and 1000°F (540°C) intermittent.

Angle bracket made of nickel plated steel provides means for firm surface mounting; can be spot welded for permanent mounting or screw mounted through holes provided.

Miniature Weatherproof Heads:

Miniature Weatherproof Connecting Head is designed for termination of single or dual thermocouples, RTD’s and strain gauges. Pipe threads are provided for probe mounting and extension wire fittings. Probe mount thread accomodates 1/4 NPT or 3/8 NPT. Cover includes gasket to seal against moisture, and chain to prevent loss. Molded of reinforced thermoset compounds, standard head can be used in ambient temperatures to 350°F (175°C); Hi-Temp head to 800°F (425°C).

Four separate connections are provided with individual circuit and polarity markings. Jab-in® terminals eliminate looped wire ends and make wiring easy and positive. Molded channels guide wire between large-head screws and copper terminal inserts. Accepts wire from 32 ga. to 14 ga.

Mounting Accessories:

Brass Compression Fitting includes body, nut and ferrule for mounting probe tubing.

Stainless Steel Fixed Fitting for brazing to probe.

Weatherproof Terminal Head:

Weatherproof Heads are rugged cast aluminum or cast iron screw cover units that are available in various NPT probe connection sizes and the choice of terminal block to fit your application.
