Best-in-class resolution in a flexible, hard-working X-ray security system.

The durable PX 6.4 Checkpoint X-ray System delivers an unbeatable combination of excellent image quality, high throughput, and flexibility. Suitable for varied applications and settings, the PX 6.4 allows operators to efficiently and accurately screen briefcases, backpacks, parcels, packages, and other small to medium-sized objects. Superb imaging capabilities facilitate the rapid detection of multiple threats,

including weapons, narcotics, explosives, and other contraband. With three conveyor lengths available, the PX 6.4 accommodates diverse space requirements, including smaller footprints. From passenger terminals and government buildings to high-risk corporate facilities, the versatile PX 6.4 provides a reliable and economical solution anywhere checkpoint security is a priority.

The L-3 Advantage

Building on the foundation of L-3's industry-leading, technological innovations, the PX 6.4 inspection system offers outstanding detection, performance, and reliability across the spectrum of checkpoint security applications.

Superb Image Clarity:

Get the Whole Picture

The advanced imaging capability of the PX 6.4 raises the standard for medium-sized X-ray screening systems. Powerful imaging technology and analysis tools allow users to quickly and accurately spot threats and contraband. L-3's patented TRI-MAT imaging discriminates between organic/inorganic materials and metallic objects.

Remarkably easy to use, the user interface gives operators and analysts the tools necessary to generate precise, richly detailed images. With a full complement of powerful image enhancement tools at their fingertips, operators can readily examine questionable objects and quickly determine the presence of true threats. The system's innovative «slide and see» continuous contrast adjustment capability lets screeners emphasize an object's smallest details, regardless of density. Its unique Best Image First™ feature automatically selects and presents the optimal view, enhancing throughput by reducing repetitive image adjustments.


Operational Flexibility

Featuring easy-to-configure software-based controls and tools, the PX 6.4 easily adapts to diverse and demanding operational requirements and evolving security challenges.

  • The PX 6.4 conveyor is available in short, medium, and long lengths to accommodate varied space requirements
  • Bi-directional operation allows two-way screening for facilities requiring inspection upon entering and exiting, such as prisons and enterprises with high theft potential.

The Operator Interface:

Intuitive Simplicity

L-3's patented operator interface provides a simple, intuitive, and flexible way for users to control the system and make the most of imaging information. Ergonomically designed to promote rapid learning and ease of use, the interface combines three-button conveyor control with a touch-sensitive pad that allows continuous heads-up operation using icons displayed on the viewing screen. The system's console is ergonomically engineered to minimize operator fatigue and reduce the physical stresses associated with prolonged screening.


Bringing It All Together

The fully networkable PX 6.4 streamlines decentralized and remote monitoring, reporting, and system management to help keep operational costs in line. Supervisors with appropriate network privileges can access and control any scanner or workstation on the LAN to send and receive bag images, TIP images, configuration settings, operator reports, diagnostics, and operational metrics. This network capability, common to all L-3 PX second generation systems, has been designed to exceed current and emerging network requirements.

Operator Tools:

Reliability at Your Fingertips

The PX 6.4 delivers an array of features that give operators the information they need to hold or clear suspicious items.

  • Proven image analysis tools allow operators to easily distinguish between organic and inorganic materials and objects having a similar appearance but different chemical composition.
  • User-friendly image enhancement tools, including continuously adjustable contrast, sharpening, and color overlay, make it easy to optimize images for maximum detection capability.
  • Threat Image Projection (TIP) option inserts fictitious threat images at periodic intervals and tracks operator responses, motivating operators to stay alert and allowing supervisors to assess the effectiveness of screening operations.
  • Customizable, user-defined Image Archiving stores up to 20,000 images.
