What Products Are Available in the Hot Runner Thermocouple Market?

Hot runner thermocouple products come in various form factors to suit different applications. Common product categories include nozzle sensors, manifold sensors, screw-in sensors, bayonet-mounted sensors, patch-type thermocouples, and customized micro probes. Sensor diameters typically range from 0.5 mm to 3.0 mm. Common specifications include Φ1.0 and Φ1.5 probes with lengths from 50 mm to 300 mm. Products like the WRNK-191 thermocouple are specifically designed for hot runner systems, using 1.0~1.6mm armored thermocouple elements. They feature KAPTON shielded or glass fiber shielded compensating wires, with insulated or grounded measuring junctions. The cold end is molded from high-temperature resin that can withstand 10 kgf of tension. Compensating wires use materials such as KAPTON shielding or glass fiber shielding. Standard connectors such as DIN and mini-plugs allow quick installation and replacement during maintenance. Sealed junction structures prevent resin leakage, oxidation, and mechanical damage. Many manufacturers provide calibrated thermocouples to ensure compatibility with different temperature controllers. Brand-matched thermocouples ensure perfect fit, stable performance, and long-term reliability. Leading hot runner brands including Mold-Masters, Husky, YUDO, Synventive, and HASCO provide dedicated thermocouples for their systems. Mold-Masters unifies M3 and M4 screw-in thermocouple interfaces, with universal specifications compatible with open gate and needle valve nozzles. Yudo integrates heating coils and thermocouples into an integrated assembly, reducing on-site installation time by nearly 40%. Chinese domestic manufacturers' product systems cover manifold button thermocouples, nozzle spring ring thermocouples, T-shaped elbow probes and miniature micro probes. Custom sizes are available for special mold designs, and many products come pre-calibrated for direct use. Type J and Type K thermocouples remain industry standards, while high-temperature types support advanced engineering resins.
