Overview
The Allen-Bradley 42EF-D2MPAK-F4 is a general-purpose RightSight photoelectric sensor engineered for industrial automation and motion control applications. This compact 18 mm cylindrical diffuse sensor combines proven Allen-Bradley reliability with a smaller, more adaptable form factor. The unit operates with a visible red LED light source and features dual complementary light/dark outputs, making it suitable for applications where space and detection accuracy matter equally.
Key Features
- Standard Diffuse Sensing Mode — detects objects directly without reflectors; ideal for opaque materials and short-range applications
- PNP Source Output — 2 complementary LO/DO outputs for flexible control logic integration
- IO-Link Enabled — provides remote configuration, diagnostics, and status monitoring for Industry 4.0 connectivity
- Manually Adjustable Sensitivity — field-tunable threshold for optimal detection margin
- Micro QD Connector — 4-pin quick-disconnect on 152 mm (6 in.) pigtail for fast installation and replacement
- Response Time 1 ms — fast detection for high-speed conveyor and motion applications
