4.2x2.2mm Coil / Cable Heaters With J Type Thermocouple And White Silicone Varnished Cable
1. Coil Heater Brief Introduction
Coil/Cable heaters could be coiled, to form coil heaters that are ideal whenever a large amount of heat is required in a confined space. Coil heaters have many applications but are mostly utilized as powerful heating cells inside hot runner nozzles in plastic injection molding.
Coil/Cable heaters are high performance mini tubular heaters that have small rectangular, square or round cross sections that are flexible and can acquire different shapes and configurations.
Coil/Cable heaters can accommodate "J" type or "K" type thermocouple sensors that could be placed internally at the tip or the middle of a heater. They can be made as well to have profiled or distributed wattage configuration.
The sheath material of standard cable heaters is stainless 304; their heating core is coiled or straight solid Nickel Chrome wire. Cable heaters can transmit up to 35 W/in2 heating capacity and can attain up to 15000F surface temperature.
