ABSTRACT:
A selector for an elevator system includes a tape vertically suspended in the hoistway that includes vertically aligned holes, a first set of strip magnets for identifying landings and a second set of strip magnets for indicating a door zone level position. A selector unit mounted on the car has guides for engaging the ends of the tape, a bar magnet and a magnetic sensor disposed on opposite sides of the holes to detect car movement, a magnetic sensor array in vertical alignment with the floor landing magnets and another magnetic sensor array in vertical alignment with the door zone magnets. Preferably, the magnetic sensors are hall effect devices and are mounted on a flat board, e.g. a printed circuit board, with a special mount piece. Similarly, the bar magnets are mounted on the printed circuit board by way of a special centering mounting piece.
