Overview
The Allen-Bradley 42GNP-9020-QD1 is a Series 9000 SmartSight diffuse photoelectric sensor designed for object detection in factory automation, packaging, and material handling applications. This model features infrared 880 nm LED transmission and a 5-pin mini integral quick-disconnect (QD1) connector, making it a direct upgrade or replacement for legacy diffuse sensors requiring infrared sensing without line-of-sight alignment.
Key Features
- 1.5 m (5 ft) maximum sensing distance with 3.5° field of view
- Infrared 880 nm transmitting LED for improved background suppression
- 5-pin mini integral QD connector for secure, tool-free connection
- Series 9000 SmartSight platform with proven industrial reliability
- Diffuse sensing mode—no reflector required
- Compact form factor with 1/2 in. NPSM thread mounting
