Voyantic has developed a dedicated coupling element for testing HF inlays and tags. The Snoop Pro HF has two different sized coupling coils integrated into the same element to provide optimal coupling for both larger and smaller HF tags. There are separate antenna ports on both sides of the Snoop Pro HF, of which the correct one is chosen depending on the tag size.
The Snoop Pro HF has a changeable shielding plate which shields out the adjacent tags and enables testing only the one of interest. The opening size in the shielding plate is chosen according to the tested tag, label or inlay size to enable optimal test setup for each product and process step. The standard delivery of Snoop Pro HF includes 5 changeable shielding plates. There are 4 plates with different standard opening sizes and a plate without an opening. Unopened plates are available for customized tooling, as well as custom tooled plates according to the customer requirements.
