Overview
The Allen-Bradley 43GT-TBB25SL024 is a transmitted beam glass fiber optic cable designed for precision sensing and industrial automation systems. This cable operates on a light transmission principle, using glass fiber to transmit light from a light source to an object and back to a receiver, making it ideal for detection applications requiring high accuracy and immunity to electromagnetic interference.
Key Features
- Transmitted beam glass fiber optic design for reliable light transmission
- 36-inch (0.91 m) standard cable length with brass threaded 5/16″ connection
- Single-mode 9/125 glass core with 3.2 mm (0.125 in) diameter randomized fiber bundle
- Stainless steel flexible conduit jacket for durability and corrosion resistance
- Temperature rating up to 500°F, suitable for high-temperature industrial environments
- One sensing tip with axial configuration for direct object sensing
