Overview
The Allen-Bradley 42GRF-9000-QD is a Series 9000 photoelectric sensor designed for reliable detection in industrial automation and motion control applications. This fiber optic photoswitch features large aperture fiber optic (LAFO) technology with infrared 880 nm light source for consistent performance in challenging environments. The sensor supports both NPN and PNP transistor outputs with a 4-pin DC Micro (M12) integral quick disconnect connector for tool-free installation.
