Dr Label Frequency: 58KHZ system: the system detects magnetic sound frequency: 58KHZ Form Factor: 45.6mm × 11.0mm Material Structure: shell ...... polystyrene (thickness 0.3mm) resonators ...... amorphous magnetic resonance materials (iron, cobalt, silicon) tablet ...... generation density polyethylene polyester (0.127mm) ...... double-sided adhesive rubber adhesive, with a total thickness of 0.140mm, the minimum peel strength 80oz / m double-sided silicon liner liner ...... magnetic sound anti-theft tags using sound waves and electromagnetic induction conditions for complex sonic induction trigger signal, by two high-performance vibration plate and a substrate composition. Use the center frequency 58KHz bandwidth by 57.8KHz-58.2KHz (0.4KHz) bandwidth for all current electronic anti narrowest * system principle, it is highly unlikely to be disturbed and cause false positives. Three (DR) systems transmit signals via composite shock vibration generated audio signal fed back to the receiving antenna discrimination identified (there is no signal found to mimic the sound of a magnetic principle)
