Overview
The Allen-Bradley 873P-D18P1-2200-D4 is an IO-Link enabled ultrasonic proximity sensor engineered for industrial automation applications requiring long-range object detection. With a 2200mm maximum sensing distance and programmable PNP discrete output, this sensor handles challenging detection scenarios involving clear, shiny, or non-reflective materials. The 18mm plastic threaded barrel design supports easy integration into material handling, packaging, food processing, and transportation systems.
