Honeywell Q340A1074/U Universal Thermocouple 30 mV (24 inch) Q390A1046/U

Product Description

The Honeywell Q340A1074/U is a universal thermocouple that produces a nominal 30 mV output with a 24 inch lead for pilot flame sensing in standing pilot gas-fired heating systems. It uses a screw-type connector and has low circuit resistance for millivolt gas control compatibility. The assembly can include an adapter and push-in clip and is suitable for use with Pilotstat safety control power units and similar valves.

• Nominal output: 30 mV (open-circuit reported 26 to 32 mV); resistance approximately 0.02 ohm
• Lead length: 24 inch; connector: screw-type (11/32-32 male connector nut reported in some listings)
• Includes adapter and push-in clip; CSA certification reported for certain listings; rated for pilot burner/standing pilot applications

Product Highlights

Universal 24 inch thermocouple for pilot flame sensing with 30 mV output, low resistance, and installation hardware included
