Advanced photo optic technology regulates carriage stopping and follow times. Users can change stopping distances to accommodate overhanging materials.

Infra-red sensor detects body heat, as a user enters an aisle, to prohibit accidental carriage movement.

The MCMS recognizes changes in current drawn by the motor and automatically halts carriage movement when it encounters increased resistance.

Protects users and items left in aisles. If the beam of light emitted between the sensors is blocked, the carriage halts.

Transponder technology allows users to program the system without special skills or the need for locks and keys. Color-coded keys communicate with the controller through radio frequency signals to initiate changes.

Motion detectors sense user movement in an aisle, thus preventing the opening of another aisle.
