Overview
The Tri-Tronics F-A-36P is a 36-inch straight glass fiber optic light guide engineered for industrial photoelectric sensing and machine vision applications. All-glass fiber construction provides superior signal integrity and allows light to be transmitted from a source to a remote sensing point with minimal loss. The straight configuration with barrel connector makes it suitable for direct-line illumination in tight machine cavities and confined sensing geometries where bend radius is not a constraint.
