PR-FB30N3 KEYENCE IP67-Rated Long-Range Retro-Reflective Photoelectric Sensor

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.

Technical Specifications:

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).
