Overview
The Allen-Bradley 43GT-TMC25SL glass fiber optic cable is a transmitted beam fiber optic cable engineered for high-temperature industrial sensing applications. This cable features a glass fiber core with combination brass and stainless steel construction, making it ideal for environments requiring durability and thermal performance. Series A designation ensures compatibility with standard Allen-Bradley fiber optic sensor systems.
Key Features
- Transmitted Beam Technology: Optimized for transmitted beam sensing mode with large aperture compatibility
- Glass Fiber Core: 3.2 mm randomized bundle fiber for reliable optical transmission and sensing accuracy
- High-Temperature Rating: 500 degrees F temperature rating for furnace, oven, and hot-surface applications
- Stainless Steel Construction: Brass/stainless steel combination connector with TM right angle threaded 5/16 in. connection
- Flexible Conduit: Stainless steel flexible conduit jacket for mechanical protection and routing flexibility
- Standard Configuration: Standard length of 0.91 m (36 in.) from tip to tip with single sensing tip
