The SET-9000 landing system uses solid state sensors to detect the presence of magnetic strips placed on a length of steel tape that runs the length of the elevator hoistway. Magnetic strips are placed along the tape in three, distinct rows. The center row is used for “leveling” magnets. The left hand row is used for up direction “slowdown” magnets. The right hand row is used for down direction “slowdown” magnets.

The sensor head containing the solid state sensors is mounted on the elevator car so that it “rides” the steel tape as the car moves, detecting and using the magnets to control floor approach and leveling.
