Overview
The Allen-Bradley 873P-D18P1-2200-D4 is a programmable ultrasonic proximity sensor designed for industrial automation, packaging, and material handling applications. This sensor features a diffuse sensing mode with a plastic threaded barrel housing and delivers reliable object detection in harsh industrial environments. The 873P series provides straightforward installation and flexible output options to integrate into control systems.
Key Features
- Extended sensing range up to 2200mm (7.87 to 86.61 inches)
- Single PNP discrete output (NO/NC pushbutton selectable)
- 18mm diameter plastic barrel with threaded mounting
- Micro QD (Quick Disconnect) 4-pin DC connector for fast field replacement
- Operating frequency 1 Hz for consistent object detection
- Programmable detection parameters for tuning and application flexibility
Technical Specifications
The sensor operates on DC power with a maximum amperage draw of 100mA, making it compatible with standard PLC 24VDC power supplies. The diffuse reflection design eliminates the need for reflector plates, simplifying integration into conveyor systems, level detection, and proximity-based automation. The micro QD connector ensures field-replaceable installation without requiring rewiring.
Typical Applications
- Packaging machinery and conveyor control
- Object presence and absence detection
- Distance measurement and level monitoring
- Industrial automation and motion control
- Material handling and sorting systems
