Overview
The Allen-Bradley 43GR-BCA73SL fiber optic cable is a glass-based sensor cable engineered for industrial photoelectric sensing applications. At 36 inches (0.91 m) in length, this cable connects large aperture photoelectric sensors to control systems with reliable light transmission. The glass fiber construction provides superior durability and temperature performance compared to plastic fiber alternatives, making it ideal for harsh manufacturing and machine tool environments.

Compatibility & Replacements
The 43GR-BCA73SL is part of Allen-Bradley’s extensive 43G glass fiber optic cable family. Direct replacements and similar length variants include other 43GR and 43GT models with different sensing tip configurations and connector types. When sourcing replacements, confirm the sensing tip style (transmitted beam vs. bifurcated), connector material (aluminum, brass, or stainless steel), and aperture size to ensure compatibility with your existing photoelectric sensor head. Rockwell Automation and authorized Allen-Bradley distributors can provide custom or alternate cable lengths and configurations. For legacy system upgrades, consult system integration documentation or contact local Rockwell Automation sales for cross-reference information.
