ELECTRONIC ARTICLE SURVEILLANCE TAG WITH TAMPER RESISTANT MAGNETIC LOCK |
摘要 |
Method for operating a magnetically controlled lock in an EAS tag (100) involves the application of a magnetic field to a plunger (322) within a housing (102) of the EAS tag. The applied magnetic field is used to cause a translational movement of the plunger in a first direction. The method can further involve causing a latch (320) to pivot about a pivot axis (807) by using the translational motion (1002) of the plunger to apply a torque (1004) to the latch. Rotation of the latch in this way causes it to move to an unlocked position which releases a locking pin (106). |
