Robertshaw 1950-532 Thermopile

The Robertshaw 1950-532 Thermopile is a heavy-duty pilot generator engineered for reliability in self-powered gas control systems. As a veteran-grade TP-75 replacement, this component features a 36-inch lead with two-wire spade connectors, providing a stable 250mV to 750mV millivolt output necessary for driving gas valves in furnaces, boilers, and commercial kitchen equipment. Built with a stainless steel outer jacket to prevent heat blistering and a copper-nickel alloy core for superior conductivity, the 1950-532 ensures precise flame detection. This gas fireplace thermopile includes a PG9 pilot adapter and a threaded mounting nut, allowing for seamless integration into various burner configurations. Whether you are servicing residential water heaters or high-output commercial fryers, this 36-inch thermopile delivers the rugged durability required for critical safety shut-off applications and consistent ignition performance in the field.

Key Benefits

• Universal Compatibility: Designed as a direct drop-in for 1950 Series and competitive millivolt systems, simplifying truck stock requirements.
• High-Temperature Durability: The stainless steel sheath resists oxidation and physical degradation in high-cycle pilot environments.
• Optimized Electrical Output: Consistently generates the 250-750mV range needed to hold in safety magnets and power millivolt gas valves.
• Installation Versatility: Includes the PG8/PG9 adapter and threaded hardware for secure mounting across multiple appliance brands.
• Maximum Conductivity: Copper-nickel alloy leads provide low-resistance transmission of the millivolt signal to the control board or valve.

Common Questions

Is the Robertshaw 1950-532 compatible with my system if it currently uses a coaxial connector?
No, the 1950-532 features a two-wire spade terminal connection. If your system requires a coaxial threaded connection, you likely need the 1951 Series (CP-2) instead.

What should I do if my millivolt reading is below 250mV during a load test?
Ensure the pilot flame is fully engulfing the top 1/2" to 3/4" of the thermopile. If the flame is correct but the output remains low under load, the internal junctions may be failing, necessitating a replacement of the generator.

Can this thermopile be used in both LP and Natural Gas applications?
Yes, the 1950-532 is gas-type agnostic; it functions based on the heat provided by the pilot flame, regardless of whether the fuel source is propane or natural gas.
