Overview
Eaton 12100RQD07 is a high-performance photoelectric sensor in the Comet 18mm tubular series, purpose-built for industrial automation, motion control, and machine vision applications. This through-beam detector uses a visible red sensing beam and employs Eaton’s Perfect Prox® technology for reliable target detection while rejecting background interference. The sensor’s industry-standard 18mm threaded body with flat sides enables flexible mounting on tubular fixtures or flat surfaces.
Key Features
- Through-beam sensing method with 20-foot (6 m) detection range for extended coverage
- Visible red sensing beam allows quick visual alignment and setup verification
- Perfect Prox® technology delivers exceptional background rejection; detects targets regardless of color, reflectance, or surface finish while ignoring nearby objects
- NPN/PNP dual output with open collector configuration; selectable light or dark operation modes
- 3.5 ms response time ensures fast, reliable detection in dynamic applications
- Solid polyurethane housing provides high resistance to shock, vibration, and environmental stress
- M12 4-pin connector interface for quick, secure connection
- Output LED indicator visible from multiple angles for real-time status feedback
