61-6872-7 Fireye Fiber Optic

Part number 61-6872-7 from Fireye, listed in Wire Ferrules & Lugs. KKM Solutions quotes this part with pricing and availability confirmed per order.

Overview The Fireye 61-6872-7 is a high-temperature quartz fiber optic bundle designed for use with industrial flame scanners. It is specifically engineered to transfer flame radiation from obstructed burner areas, where a direct line of sight is unavailable, to scanner electronics located outside the windbox. This 7-foot bundle is essential for maintaining reliable flame detection in complex burner configurations where movable vanes or air compartments might block a conventional scanner’s view. Features High-temperature quartz optics capable of withstanding extreme furnace environments. Flexible stainless steel outer housing to protect the bundle and facilitate versatile routing. Distinctive “hot” and “cold” end markings (indicated by “H” or “C” etched on ferrules) to ensure correct orientation and alignment. Blue marker on the cold end for quick identification during installation. Designed to maintain signal integrity even in installations with heavy physical obstructions. Specifications Model Number: 61-6872-7 Length: 7 feet (2134 mm) Optical Material: High-temperature quartz Maximum Temperature (Hot End): 752 degrees F (400 degrees C) Manufacturer: Fireye Shipping Weight: Approximately 1.0 – 5.0 lbs (depending on carrier assembly) Compatible Scanners: InSight II (95DSS3), 95UV, 85UV, and 45UVFS series Applications The 61-6872-7 is primarily used in power generation and large industrial boilers where burners have tilting nozzles or internal obstructions like diffusers. It is ideal for monitoring individual burner flames in systems where they might otherwise be obscured by the furnace fireball. Common applications include utility boilers, process heaters, and complex combustion systems where scanner electronics must be protected from high windbox temperatures.
