Overview
The Allen-Bradley 42GRF-9002-QD fiber optic sensor is a standard on/off photoelectric sensor from the Series 9000 lineup. It features large aperture fiber optic detection, 70-264V AC/DC supply, SPDT electromagnetic relay output, and mini quick-disconnect connector with 2m cable. This model is engineered for industrial automation applications requiring precise object detection through light-transmitting fiber optic cables.
Key Features
- Large aperture fiber optic design for extended sensing flexibility
- 70-264V AC/DC operating voltage with SPDT relay output
- Infrared light source for reliable detection independent of ambient light
- Mini quick-disconnect connector for fast installation and replacement
- 2-meter sensing cable included
- Standard on/off switching—no teach or diagnostic modes required
Technical Specifications
The 42GRF-9002-QD is designed for rugged industrial environments where fiber optic cable routing is required. It features high operating margins for excess gain and a fiber optic cable locking mechanism to ensure secure connections in vibration-prone settings.
Typical Applications
- Object detection on machinery and production lines
- Position sensing in constrained or harsh environments
- Presence verification in conveyor systems
- Material level detection using remote fiber optic probes
- Safety interlocks requiring robust light-based sensing
