Ostra & Shell D40
The Crosspoint Ostra Shell D40 is a high-performance Electronic Article Surveillance (EAS) hardware solution designed for multi-frequency retail environments. This security tag integrates dual-resonator technology, allowing it to function simultaneously on 8.2 MHz Radio Frequency (RF) and 58 kHz Acousto-Magnetic (AM) bandwidths. This technical versatility ensures that procurement managers can deploy a single tag across diverse store locations regardless of the existing antenna infrastructure. The architecture utilizes a patented Total Enclosure Design (TED) that protects the internal pin assembly from unauthorized manipulation.
Key Features
