QL56 Series

Overview

Reliably detects luminescent plastics, coatings, lubricants, and marks on irregular or reflective surfaces. Housed in IP67-rated aluminum housing for use in rugged industrial environments.

  • High-power UV emission provides a consistent beam for improved sensitivity and reliable detection
  • Emitted spot is a line of light formed by 6 UV LEDs
  • Three push buttons to adjust the sensor’s switch point sensitivity and enable or disable a 20 ms off delay
  • Variable operating distance depending on model: 15, 30, or 40 mm
  • 5 position swivel QD connector to accommodate cramped mounting situations
