摘要

Device for detecting the passage of an electromagnetic marker comprises a thin antenna support (4) with a housing (11) at one end (4a) of the support that receives a bar (12) of low voltage LEDs (13). The support contains a wire antenna (6) that is arranged within it for the emission or receipt of a high frequency signal to or from a transponder or marker. The LEDs serve to illuminate the antenna support. The transparent supports can be equipped with engraved markings or inscriptions to improve their aesthetic appearance.
