Allen-Bradley 47SN1-4000 Photoelectric Receiver

The Allen-Bradley 47SN1-4000 Photoelectric Receiver is a dedicated optical receiver used in industrial automation to detect objects by sensing light signals. As the companion to an emitter, it converts a light beam into an electrical output that can be wired to a PLC or other control hardware. The 47SN1-4000 designation identifies this specific receiver model within Allen-Bradley’s photoelectric sensor family, enabling integration with compatible emitters and standard mounting layouts in common sensing configurations. This device enables non-contact object detection in environments where speed, cleanliness, and reliability are required, and it is commonly employed on automated manufacturing lines, packaging stations, and material-handling equipment to sense presence or absence of items. When selecting a receiver for a system, engineers focus on compatibility with the emitter type, sensing range, response behavior, and environmental suitability; refer to Allen-Bradley technical documentation for exact electrical ratings, wiring conventions, and installation guidelines.
