DF-G1 Series


High performance dual-display fiber amplifier. Features simple set-up and configuration and stable performance.

  • Easy to read dual digital displays simultaneously show signal level and threshold
  • Simple user interface ensures easy sensor set-up and programming
  • Expert TEACH and SET methods ensure optimal gain and threshold for all applications, especially low contrast applications
  • User has full control over all operating parameters
    • Switch point threshold
    • Light Operate or Dark Operate
    • Output timing functions
    • Gain level
    • Response speed
  • Thermally stable electronics minimize warm-up drift and reduce the effect of side-by-side mounting of multiple fiber amplifiers
  • ECO (economy) display mode reduces amplifier power consumption by 25%
  • Cross talk avoidance algorithm allows two fiber assemblies to operate in close proximity for many applications
  • Response speeds as fast as 200 µs
  • High performance 32 bit microprocessor with a 12 bit ADC
  • Works with any 2.2 mm fiber optic cable. Find the right fiber for your application with our plastic fiber selection guide
