The 4SAFE is a failsafe active infrared sensor which functions by distance measuring.

Onboard of  a swing or revolving door’s leaf it brings safety to the users by avoiding their coming into contact with the moving door. The three-dimensional area of the 4SAFE  makes it particularly suitable for protecting people with disabilities.
