NEEDLE DETECTOR

HN-870CS, HN-780GS, HN-880C/CS, HN-790G/GS, HN-2870CS, HN-2780GS, HN-2880C/CS, and HN-2790G/GS have the? Super Fine mode. This mode allows adjustment of conveyor speed from 40 m/min to 15 m/min in 1 m/min increments.
In recent years, the number of apparel accessories and materials (petroleum-based materials) has been diversifying, increasing the number of products that are detected incorrectly by the inspection machine.
This is partly due to the need to strengthen the needle detection itself (increase the sensitivity level).
Hashima has discovered that the response due to these false positives and the response due to normal magnetic materials varies depending on the belt speed.
Using this, Hashima has made it possible to reduce the conveyor speed in superfine mode and allow accessories to pass through while maintaining the set sensitivity level.
This is not simply a matter of reducing the belt speed.

Products with no possibility of false positive reactions can still be read with more efficient operation than other companies’ machines with the fast conveyor speed (40 m/min) which is a characteristic of Hashima’s needle detector.
