The Cross Point Ostra & Shell D40 (
OSTRA D40 and
SHELL D40) are premium 8.2 MHz RF hard tags designed for retail electronic article surveillance (EAS) systems. These tags provide effective theft deterrence, durable construction, and compatibility with most RF systems.
They feature secure locking mechanisms and optimized detection profiles for both mono and dual-antenna setups. While similar in form factor and frequency, they differ slightly in internal design and shell construction.
Common Specifications for Both Tags
- Tag Type: RF (Radio Frequency) EAS Hard Tag
- Operating Frequency: 8.2 MHz
- Technology: Acousto-Magnetic (for AM variants), but D40 is strictly RF
- Detection Method: Passive resonance circuit detectable by compatible RF systems
- Application Areas: Fashion, sportswear, accessories, general retail
- Tag Shape: Circular shell design
- Color Options: Glossy black, glossy white, or custom (on request)
- Pin Compatibility: 20 mm steel or plastic pin
- Lock Type: Standard mechanical clutch or optional SuperLock / HyperLock
- Deactivation: Requires manual detacher; not deactivatable like soft labels
- Durability: Impact-resistant ABS shell, resistant to tampering and corrosion
- Temperature Tolerance: Operational up to 50°C, storage up to 70°C
- Moisture Resistance: Yes, suitable for standard retail indoor humidity

- Magnetic Detacher Compatibility: Works with most standard and SuperLock detachers
- Deactivation/Removal: Manual detacher only; cannot be turned off electronically
Use Cases & Advantages
- Ideal for apparel, accessories, sports gear, and boxed items
- Low false-alarm rates due to tuned resonator coils
- Consistent tag performance across antenna models
- Aesthetic and unobtrusive on merchandise
- Long lifecycle with reusability for several years
Packaging & Logistics
- Standard Packing Unit: 1,000 tags per carton
- Inner Packaging: 100 tags per sleeve or tray
- Carton Weight: Approx. 15–16 kg per box
- Labeling: Includes frequency marking, batch ID, and serial (optional)
Summary
The
OSTRA D40 is optimized for higher-end retail environments requiring strong tamper resistance and extended detection range, while the
SHELL D40 offers a rugged yet cost-efficient option with slightly reduced performance but full compatibility with standard RF systems. Both deliver high detection reliability, easy reuse, and strong visual deterrence in a compact design.
Meta Description
Cross Point Ostra & Shell D40 are 8.2 MHz RF security tags designed for retail EAS systems. Featuring durable ABS shells, up to 2.05 m detection range, strong tamper resistance, and SuperLock options, they provide reliable, reusable anti-theft solutions for fashion and general retail.
