In case of a pressure drop inside the cabin of a passenger plane, oxygen masks are automatically released from the ceiling above each passenger. They rest in a compartment, which is unlocked by means of a solenoid locking unit from KUHNKE, which is made completely from materials certified for aviation purposes. At the core of this unit is an integrated holding solenoid, which keeps the compartment locked as long as no currant is applied. An electrical impulse will immediately release the mechanism and open the lock. This application from KUHNKE holds a leading position in the aviation industry. It is characterized by optimized power rating and extremely low weight.
