CGF50‑R4NA – Retro-Reflective Photoelectric Sensor (4 m Range, NPN-NO)

GH₵500.00 GH₵700.00

The CGF50‑R4NA is a square-style retro-reflective photoelectric sensor designed for accurate long-range object detection up to 4 meters. Using a reflector to bounce emitted light back to the sensor, it provides stable and precise detection of opaque targets—even in dusty or ambient-light conditions.

This model features a 3-wire NPN Normally Open (NO) output configuration, allowing for easy integration into most PLCs and digital input systems requiring sinking input logic.


✅ Key Features

  • Sensing Principle: Retro-reflective – detects when beam is interrupted between sensor and reflector

  • Sensing Range: Up to 4 meters with standard reflector

  • Output Type: NPN, Normally Open (NO)

  • Response Time: < 8.2 ms – fast switching suitable for high-speed applications

  • LED Indicator: Built-in red LED for visual output status

  • Protection: IP65-rated enclosure, reverse polarity and surge protection

  • Design: Durable 50 × 50 mm ABS body with standard M18 mounting holes
