Watlow AFED0HA020E3030 Thermocouple 0.063 Inch Diameter 2 Inch Sheath Special Type J

The Watlow AFED0HA020E3030 Thermocouple is a mineral-insulated (MI) sensing element designed for industrial temperature measurement, delivering accurate Special Type J (Iron-Constantan) signals in high-temperature manufacturing environments where precise feedback is critical. It features a 0.063 inch (1/16 in.) diameter stainless-steel sheath and a 2 inch probe, providing a compact profile for confined sensing locations while maintaining chemical compatibility and resilience suitable for long service in demanding processes. As a member of the AF Style Metal Transition Thermocouple family, this sensor combines mineral insulation with a metal-transition construction and is commonly installed in heat-treat furnaces, industrial ovens, plastics processing equipment, packaging machinery, and laboratory systems that require dependable Type J temperature feedback. Maintenance teams, original equipment manufacturers, and system integrators rely on AFED0HA020E3030 for sensor replacement, control-system repairs, equipment retrofits, and preventive maintenance programs, delivering reliable temperature monitoring across plastics, metalworking, food processing, and general process-heating applications.
