Project Description

TFA/FFA.1E Straight plug, cable collet and nut for fitting a bend relief

TFA.1E unipole coaxial lemo compatible connectors

1, TFA/FFA.1E unipole coaxial connector brief introduction:

TFA.1E Push-Pull unipole coaxial Connectors alternative with lemo FFA.1E connector but cheaper, offer a reliable connection for data, signal, and power transmissions.

2. TFA/FFA.1E lemo alternative connector description:

  • Small size, quick insertion and security of the Push-Pull self-latching system
  • There are straight type, elbow (90°) type and other different types of plugs;
  • High frequency: transmission frequency is 3MHZ ∽ 30MHZ;
  • Many functions: in addition to the role of the bridge, it also has the function of processing signals, such as filtering, phase adjustment, mixing, attenuation, detection, limiting, etc.
  • Low standing wave, low loss: meeting the needs of weapon systems and precision measurement;
  • Large capacity, high power: mainly to meet the development needs of the information super high way.
