Overview
The Allen-Bradley 42GNC-9200-QD1 is a photoelectric sensor from Rockwell Automation’s Photoswitch Series 9000 line. This clear object photoswitch delivers straightforward on/off control for industrial automation, motion control, and material handling applications where accurate object detection is essential. The compact sensor integrates a quick-disconnect (QD) connector for simplified installation and field replacement.
