Description
Eaton E51KF233 - The Glass Fiber Optic Cables enable light transmission through a bundle of fine glass fibers, offering flexibility to curve through equipment while minimizing signal loss. Two cable types are available: Duplex fibers for diffuse reflective sensing, where one cable is required for sensing, and single fibers for thru-beam sensing, necessitating two separate cables for source and detector light. These cables are designed for remote sensing in space-restricted or tight viewing angle areas and can withstand high temperatures up to 480°F. They come in various styles and lengths, with options for PVC or stainless steel jackets, catering to different application needs. Larger fiber bundles offer increased excess gain for longer sensing ranges, while smaller sizes are ideal for detecting extremely small targets. The Glass Fiber Optic Cables provide a versatile solution for diverse sensing requirements.
