High performance contrast sensor for colored registration mark detection

  • Fastest and accurate low jitter model (TL46-WJ)
  • Color mode enhanced model (TL46-WE)
  • Wide-spectrum RGB or white LED emission
  • 5 different models: basic, standard, enhanced, low jitter, color mode
  • Automatic, manual and dynamic settings
  • 10, 15, 20, 30 or 50 kHz switching frequencies
  • Very low jitter down to 7µs (TL46-WJ...)
  • NPN/PNP and analog outputs
  • Standard mounting, M12 connector rotatable to 5 positions
