Foreign object X-ray inspection instrument

Non-destructive testing


This foreign object X-ray inspection instrument for shoes, apparel, sundries and bags features images from two different directions acquired simultaneously. RV-5020DV has two line sensors that enable collection of dual images at 0° and 20° at the same time, with the results presented on two separate screens, decreasing the possibility that foreign objects will be overlooked. It is possible to set the brightness and contrast individually for the two screens, making this system effective for the detection of foreign matter of various shapes and sizes. Like other instruments in the RV series, the RV-5020DV features simple operation, and the system is housed in a compact cabinet.

Two line sensors

RV-5020DV has two line sensors that enable collection of dual images at 0° and 20° at the same time.


RV-5020DV uses two straight line sensors, which improves inspection accuracy

Easy operation

The RV-5020DV is equipped with a dedicated, embedded operation panel. Operation is so simple that anyone can use it easily.


RV-5020DV has two line sensors that enable dual images from angle 0° and 20°

Various image processing functions

With one button, you are able to zoom in or out images, adjust contrast and brightness, reverse white and black and display images in colors.

Compact enclosure

The tube-below design makes the RV-5020DV cabinet compact. This allows the RV-5020DV to be smaller.

High-energy X-rays

The X-ray tube voltage can be as high as 110 kV, making it possible to inspect thick metal and shoe soles.

Two-person evaluation

Having two judges decide whether a product passes inspection (OK or NG) improves the accuracy of the examination process.

File management

OK and NG images are automatically saved with different file names, and you can easily search and review files later.

Continuous inspection mode

Examine 5000 pairs of low shoes in 8 hours (excluding evaluation time)

Inspection in a short time

The captured image of the next inspection item can be held during image evaluation, creating an efficient inspection process.


Summarizing results for clients is facilitated by a convenient reporting function.
