Harder, Better, Faster, Stronger! LCS 75 Compact Unit IP66 - The modern installation through plug & play

Water-proof and industrial luminaires IP66 cannot be connected any faster. Here is the proof:

The modern electrical connection of IP66 luminaires is four times faster than conventional installation with the LCS 75 connector. As the luminaire does not need to be opened, it is guaranteed to retain its IP protection even after connection. The connector is also suitable for use in environments containing ammonia.

The range includes:
  • 3 and 5 pole connectors with release buttons
  • 5 pole connector without release buttons for housing hole M20
  • protective caps for unused terminals with through-wiring
  • special versions with integrated strain relief
