Q390A thermocouples sense the 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 to generate a small amount of DC power, measured in millivolts.

Features:

• Push-in clip, split nut, and adapter assembly for easy pilot burner installation.
• Male nut connector for Pilotstata® safety control power units.
• Available in a variety of lead lengths.
