Overview
The Allen-Bradley 42GRF-9002-QD Series B is a fiber optic photoswitch infrared sensor built for precision detection in industrial automation systems. The 42GRF-9002-QD uses transmitted beam technology to detect the presence or absence of objects through fiber optic cables, making it ideal for applications where space constraints or harsh environmental conditions prevent use of standard photoelectric sensors. This sensor is part of Rockwell Automation’s Series 9000 Photoswitch product line, trusted across manufacturing, packaging, and material handling operations.
Key Features
- Fiber optic transmitted beam design for flexible sensing in confined or harsh environments
- Quick-disconnect (QD) connector for fast installation and maintenance
- Series 9000 proven platform with widespread industrial adoption
- Infrared wavelength detection for reliable object identification
- Standard on/off output configuration
- Compact, modular construction for easy integration into control systems
Technical Specifications
Specific electrical and mechanical specifications for the 42GRF-9002-QD vary by configuration. For exact voltage, output type, sensing distance, and connector pinout details, consult the Rockwell Automation Series 9000 technical documentation or contact your system integrator.
