1.36" Armored Thermopile — 750 mV output, 2.2" lead wire with spade terminals for 2-screw mount Key benefits Reliable millivolt signal: Produces a consistent 750 mV output for stable control and sensing in millivolt systems. Durable protection: Armored construction shields the sensing element from mechanical damage and environmental exposure, improving service life in demanding installations. Easy installation: 2.2" lead wire with pre-attached spade terminals simplifies connection to controllers or gas valves and is designed for two-screw mounting for a secure fit. Compact form factor: 1.36" overall size fits tight pilot assemblies and restricted spaces where larger sensors will not. What it does and why you need it The thermopile converts thermal energy from a pilot flame or heat source into an electrical signal (750 mV) used to confirm flame presence and drive millivolt controls. Use this component where a stable millivolt input is required for gas valves, safety circuits, or control modules. Its armored design helps protect the sensor during installation and operation, reducing the risk of damage that can cause intermittent readings or failure. Important attributes Size: 1.36" sensing assembly — compact for pilot/light assemblies and confined spaces. Output: 750 mV nominal — suitable for millivolt safety and control applications. Wiring: 2.2" lead wire with spade terminals — ready for quick connection. Mounting: Designed for a two-screw mount for straightforward replacement or retrofit. Typical applications Gas-fired furnaces and boilers: Replace or upgrade pilot flame sensors and thermopiles used in standing-pilot systems. Water heaters and heaters: Provide reliable millivolt feedback to gas valves and safety circuits. Industrial burners and pilot assemblies: Compact, protected sensor for tight spaces and rugged environments. Installation notes Designed for two-screw mounting and direct connection via spade terminals; verify physical dimensions and terminal spacing against your device before installation. Intended for millivolt control systems requiring a 750 mV thermopile signal. Do not alter wiring polarity when connecting to control inputs. This thermopile provides a compact, protected, and installation-ready solution for applications that require a steady 750 mV millivolt signal and two-screw mounting with spade-terminal connections.
