Honeywell Thermocouple Q390A1061, 36"

Features thermocouples generate a thermoelectric current that senses a pilot flame on gas-fired heating systems. the pilot flame heats the tip of the thermocouple, producing a temperature differential between it and the base. this temperature difference generates a small amount of dc power, measured in millivolts push-in clip, split nut, and adapter assembly for easy pilot burner installation spade or quick-connect terminals available for millivolt gas control connections male nut connector for pilotstat safety control power units available in a variety of lead lengths.
