The Honeywell Q340A1066 30mV thermocouple comes with 11/32 32 male connector nut connection and 18 in. leads. This thermocouple generates 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.
