Overview
The Eaton 13106RQD03 is part of Eaton’s Comet Series photoelectric sensors, a complete line of high-performance 18mm tubular devices engineered for industrial sensing applications. The diffuse reflective detection mode makes this sensor ideal for applications where target surfaces vary in reflectance and color, providing straightforward, cost-effective object detection without the need for retroreflectors or separate transmitter/receiver units.
Key Features
- Diffuse reflective detection mode for flexible sensing without retroreflectors
- 18mm industry-standard tubular housing with flat sides for versatile mounting
- Solid polyurethane encapsulation provides high shock and vibration resistance
- Light/Dark operation switch with gain control for quick optical alignment
- LED indicators (red for misalignment, blue for signal strength) enable fast commissioning
- Wide DC voltage range supports multiple industrial power supplies

Replaces / Drop-In Replacement For
Verify specific replacement compatibility with your original equipment documentation. The Eaton Comet series shares a standardized 18mm housing family; however, direct interchangeability depends on wiring type (2-wire, 3-wire, 4-wire), output configuration (NPN/PNP), and sensing range. Always confirm connector pin configuration before substitution.
Works With
- Eaton/Cutler-Hammer distributed I/O modules and remote terminals
- Connector cables and adapters in Eaton’s standard 18mm sensor lineup
- Industrial networks supporting discrete sensor inputs (Ethernet/IP, PROFINET, Modbus)
- Standard PLC discrete input modules rated for sensor voltage and current
