Double Key Cylinders with Independent Core Rotation for Dual-Entry Portals
Engineering Overview: Technical analysis of double Euro cylinders with independent internal core couplings for security air-locks and prison sally ports.
Technical & Engineering Specifications
| Material | Hardened 40Cr Steel Cam & Brass Body |
|---|---|
| Standard | EN 1303 Class 6 |
| Operation | Isolated core rotation (No key back-drive) |
| Cylinder Type | Independent Dual-Clutch Euro Double Cylinder |
Independent Core Coupling
In prison sally ports, operating the exterior key must not rotate the interior key plug, preventing key traps.
Independent Core Mechanics
- Dual Clutch Separator: Each plug rotates independently, driving the central cam without back-driving the opposing key plug.
