PZ-G62N Retro-Reflective Photoelectric Sensor for Transparent Object Detection
The Keyence PZ-G62N is a built-in amplifier photoelectric sensor from the PZ-G series. It uses a retro-reflective method for transparent object detection. The sensor pairs with an R-2L reflector and reaches a detecting distance of 0.1 to 1 m. An infrared LED light source supports stable detection in packaging, labeling, and clear bottle lines. The rectangular housing fits tight machine spaces. IP67, IP69K, NEMA 4A, 6, 12 ratings support harsh washdown areas.
