Klüber Klüberalfa KR 3-730

Protecting and lubricating fluid for plug-in contacts

Application Klüber Klüberalfa KR 3-730

Klüberalfa KR 3-730 is suitable for the large-batch oiling of plug-in contacts of different shapes and materials which have to the meet high requirements in e.g. telecommunications, automation technology or car manufacture. In-house tests have shown that the protecting effect of Klüberalfa KR 3-370 is best on lead-free tin alloys. Optimum results are achieved with contact forces below 5 N.

Product Description

Details

Performance, Features & Benefits of Klüber Klüberalfa KR 3-730 are:

  • Easier and safer assembly due to reduced plug-in/unplug forces
  • Increased operativeness of contacts due to a new type of additive
  • Easier quality control due to integrated fluorescent indicator
  • Cost saving, fully automatic, large-batch application

Product Description Klüber Klüberalfa KR 3-730

Klüberalfa KR 3-730 is a lubricating fluid based on PFPE oils that was especially developed for automatic minimum-quantity lubrication of large batches of plug-in contacts. Klüberalfa KR 3-730 reduces assembly forces and protects surfaces effectively against tribological ageing without increasing contact resistance. A newly developed additive package prevents wear due to vibration (fretting corrosion) or frequent plug cycles, thus considerably increasing the operativeness of the lubricated contacts. Klüberalfa KR 3-370 contains fluorescent indicators which make automatic, visual quality controls easier.

Application notes

We recommend applying Klüberalfa KR 3-730 by means of automatic spraying systems or immersion bath onto the clean contacts. A low-boiling, non-flammable solvent ensures quick drying. An average film thickness of approx. 2 µm is sufficient in most cases. Before applying Klüberalfa KR 3-730 the contacts should be free of contamination and punching oil residues in order to ensure good wetting of the entire contact surface. For detailed information on spray application, please seek consultation by one of our sales engineers. In general, Klüberalfa KR 3-730 is compatible with plastics, however due to the great number of different plastics we recommend checking compatibility prior to series application.
