    摘要: Modular sweep detectors, systems, and methods for securing items of merchandise from theft and are provided. In one example, a modular sweep detector includes a housing configured to engage a pusher of a pusher device and a sensor configured to engage a biasing member of the pusher device. The biasing member is configured to be biased in response to movement of the pusher. The sensor is configured to detect movement of the pusher for determining if a predetermined number of items of merchandise have been removed from the pusher device.

    摘要: Anti-sweep devices which are operable to contain a plurality of packages disposed on a base within a cover or housing, and dispense packages one at a time. A door for accessing a product such as a package is disposed at a front portion of the device. The base includes a pusher axially aligned with the long axis of the base. A sled, lift plate, product retention tab, a sled biasing element and a means for retarding a biasing force imparted by the sled biasing element are positioned below the base. The sled is slidably oriented along the longitudinal axis of the base and has a door contacting end and sled biasing element couple to the opposite end. The sled is engageable to the means for retarding a biasing force imparted by the sled biasing element. In use, opening the door to remove a product or package pushes the sled against the resistance of the sled biasing element, compressing it, and the lift plate and product retention tab are urged upward via the lift plate and through an aperture formed in the base to stop the next product or package from advancing toward the door.
