61-4842-3 Fireye Fiber Optic

Overview

The Fireye 61-4842-3 is a 5-foot glass fiber optic bundle designed for transmitting flame signals from combustion chambers to remotely mounted flame scanners. This component is essential for installations where a direct line of sight is obstructed or where extreme heat prevents the surface mounting of a standard scanner. By utilizing flexible glass fibers, it allows for the precise positioning of the sensing head while protecting sensitive electronic components from high-temperature environments.

Features

• Flexible glass fiber construction optimized for infrared (IR) light transmission.
• High-temperature resistance to allow the scanner head to be positioned within the burner area.
• Remote mounting capability to protect the scanner electronics from mechanical damage and thermal stress.
• 5-foot (1524 mm) length for versatile routing around burner apparatus, diffusers, and sight pipe misalignments.

Specifications

• Model Number: 61-4842-3
• Length: 5 feet (1524 mm)
• Material: Glass fiber bundle
• Type: IR light guide
• Compatibility: Designed for use with Fireye 95IR, 85IR, 45FS, 45RM, and 48PT2-100X series scanners.
• Shipping Weight: Approximately 1.5 – 5 lbs (depending on packaging)

Applications

The 61-4842-3 bundle is primarily used in industrial and commercial burner/boiler applications where sight pipe alignment or burner internal components like diffusers would otherwise block the flame signal. It is an ideal solution for monitoring flames in high-heat zones where a conventional surface-mounted scanner cannot be used. It is frequently employed with IRFK fiber optic scanner assemblies to extend the reach of the flame safeguard system in complex burner configurations.
