Panasonic CX-493 Photoelectric Sensor

The Panasonic CX-493 (Part No. UCX493) is a high-precision retroreflective photoelectric sensor, engineered for stable and reliable object detection over distances up to 5 meters (16.404 ft) when used with the RF-230 reflector. Optimized for opaque or translucent objects ≥ Ø50 mm, this sensor delivers exceptional accuracy with 0.5 mm repeatability and a 1 ms or faster response time. With a NPN open-collector output, the unit allows for flexible integration via Light-ON or Dark-ON selectable modes and includes short-circuit protection for safe operation.

Built to withstand demanding industrial conditions, the CX-493 features IP67-rated protection, shock resistance up to 50 G, and vibration resistance across all axes. It incorporates helpful diagnostics with orange and green LED indicators for operation and stability, while the continuously adjustable sensitivity ensures optimal setup. Certified for EMC and RoHS compliance, this sensor is suitable for a wide variety of sensing tasks in automation environments.

Applications :-

  • Long-range object detection: Accurately senses items up to 5m with reflector.
  • Factory automation: Maintains stable sensing even under strong ambient light.
  • Packaging and logistics lines: Detects larger or translucent packages in motion.
  • Close sensor mounting: Built-in interference prevention allows adjacent use.
  • Dusty or wet settings: Operates reliably with IP67 protection and industrial-grade durability.

Precautions :-

  • Ensure Correct Wiring: Incorrect connections can cause sensor failure
  • Avoid Overvoltage: Operating within 10-30V DC prevents damage
  • Protect from Extreme Heat: Avoid installing near high-temperature sources
  • Regular Cleaning: Keep the optical lens free from dust and debris for optimal performance
