KEYENCE PR-FB30N3 IP67-Rated Long-Range Retro-Reflective Photoelectric Sensor
Product Description: KEYENCE PR-FB30N3
The KEYENCE PR-FB30N3 is a compact retro-reflective photoelectric sensor designed for industrial automation applications. It detects objects by measuring the reflection of an infrared light beam from a dedicated reflector, enabling non-contact detection of presence, position, or count of targets. This sensor is widely used in manufacturing lines, packaging machines, logistics sorting systems, and safety monitoring applications.

Features:
Long Detection Range:
Reliable detection up to 30 meters, ideal for large-scale machinery or remote monitoring.
High Reliability:
IP67 rating ensures stable operation in dusty, oily, or wet environments.
Flexible Output Configuration:
NPN/PNP dual-polarity output compatible with PLCs and control systems.
Anti-Environmental Interference:
Built-in optical filtering minimizes false triggers from external light sources (e.g., sunlight, fluorescent lamps).
Fast Response:
Millisecond-level response time supports high-speed production lines (e.g., packaging, assembly).
Applications:
Industrial Automation:
Object counting on conveyors; robot pick-and-place positioning.
Logistics Sorting:
Parcel detection, automated sorting system activation.
Safety Monitoring:
Perimeter intrusion detection, door/gate status monitoring.
Packaging Machinery:
Box sealing verification, label alignment detection.
Notes:
Reflector Compatibility:
Requires a dedicated reflector for optimal beam return stability.
Ambient Light Avoidance:
Shield from direct exposure to strong light sources (e.g., sunlight, halogen lamps).
Wiring Isolation:
Separate power and signal lines to prevent electromagnetic interference (EMI).
