Part number 61-6647 from Fireye, listed in Photoelectric Sensors. KKM Solutions quotes this part with pricing and availability confirmed per order.

Overview The Fireye 61-6647 is a 3-foot (914 mm) outer carrier assembly designed for use with Fireye fiber optic flame scanner systems, such as the InSight II. It serves as a protective permanent housing for fiber optic inner carrier assemblies (glass or quartz) in industrial burner environments where a direct line of sight to the flame is obstructed by internal burner components. This assembly is part of a modular system that includes the outer carrier, an inner carrier bundle, and a scanner electronics assembly. Features Provides a rigid and flexible stainless steel protective conduit for delicate fiber optic bundles. Designed to be permanently fastened to the boiler or burner housing. Compatible with both quartz and glass fiber optic inner carrier assemblies. Enables flame monitoring in challenging environments with moving vanes or air compartments. High-temperature resistant construction suitable for industrial combustion chambers. Specifications Model Number: 61-6647 Nominal Length: 3 feet (914 mm) Material: 303 Stainless steel mounting head; flexible stainless steel front; rigid stainless steel rear. Mounting: 1-1/2 inch hexagonal mounting head. Compatibility: Used with Fireye InSight II and similar fiber optic scanner series. Shipping Weight: Approximately 3.0 lbs (1.4 kg). Applications The 61-6647 is used in commercial and industrial boiler applications where the target flame may be obscured or moved away from the line of sight of conventional surface-mounted scanners. It is specifically employed in systems utilizing fiber optic light guides to bring flame radiation from the furnace interface to a detector located outside the windbox. It is commonly used in power generation, large-scale HVAC, and process heating industries.
