DIN 1.0/2.3 Connectors were developed for the European telecommunications market in the 1990s. They are available in 50 ohm and 75 ohm options. The 50 Ohm DIN 1.0/2.3 connectors can operate at frequencies up to 10 GHz and the 75 ohm DIN 1.0/2.3 connectors can operate up to 4 GHz.

DIN 1.0/2.3 connectors have a compact design which makes them a great option for space constrained and high-density applications like digital broadcast, CATV distribution, base stations, data communications, encoders, video processors and filters & wireless components. 

The connectors are standardized according to DIN 41626, DIN 47297, and NFC 93-571 international specifications.

They are available in four coupling mechanisms:

  • Type A - Screw-on mechanism with coupling nut
  • Type C - Slide-on coupling with centering sleeve
  • Type E - Snap-on coupling with retention clip
  • Type F - Quick lock

Key Features:

  • Impedance: 50 Ω, 75 Ω
  • Frequency Range: DC-10 GHz (50 Ohm), DC-4 GHz (75 Ohm)
  • Coupling Mechanism:
    • Quick Lock Coupling
    • Screw-on Coupling
    • Slide-on/Push-on Coupling
    • Snap-on Coupling
  • Connector Durability: 500 matings
  • Temperature Range: -40⁰C to +155⁰C
  • Interface Standards: CECC 22230, DIN 47297, IEC 61169-29
