A deactivator/detector is a device used in retail environments to deactivate or detect security labels or tags attached to merchandise. These labels or tags are typically used to prevent theft or unauthorized removal of items from the store. The deactivator function is used at the point of sale to deactivate the security label or tag, while the detector function is used at the store exit to identify any active security labels or tags that haven't been properly deactivated.

Here's a breakdown of the deactivator and detector functions:

1. Deactivator: The deactivator function is used during the checkout process at the point of sale. It has a deactivation zone where the security label or tag on the merchandise is passed over or placed in close proximity. The deactivator emits a specific signal or electromagnetic field that deactivates the label or tag, rendering it inactive. Once deactivated, the label or tag will no longer trigger alarms at the store exit.

2. Detector: The detector function is typically placed at the exit of a retail store, where customers pass through while leaving. The detector scans for any active security labels or tags that have not been properly deactivated. If an active label or tag is detected, it triggers an alarm or alert to notify store personnel of a potential theft or unauthorized removal.

The deactivator and detector work together as part of an electronic article surveillance (EAS) system. This system helps prevent shoplifting and reduces shrinkage by deterring thieves and providing a security measure at the point of sale and store exit. It allows for smooth customer transactions while ensuring that security measures are in place to protect the retailer's inventory.

Deactivators and detectors are available in various forms, including standalone devices, integrated systems with point-of-sale systems, or as part of self-checkout stations. They can be customized to work with different types of security labels or tags, such as magnetic, radio frequency (RF), or acousto-magnetic (AM) tags.

Overall, deactivators and detectors play a crucial role in retail loss prevention strategies by deactivating security labels or tags during checkout and detecting any active tags at the store exit, helping retailers maintain security and reduce theft.
