Abstract: The present invention describes a stop device for stopping a carrier traveling in a pneumatic tube. The invention also includes a terminal comprising the stop device. The stop device includes a pneumatic tube having an exhaust aperture and a shutoff aperture and a pressure sensing monitor in fluid communication with the shutoff aperture. The pressure monitor senses the pressure change in the shutoff aperture caused by the carrier's movement past the shutoff aperture and activates a switch shutting off the pneumatic source. The carrier impacts an end stop and settles down on a catch which was also activated by the pressure monitor. The carrier is held in front of a door through which the carrier may be readily retrieved.
