Ultra-small specifications
The sensor is only the size of a fingertip, ultra-small and ultra-thin, suitable for installation in various narrow spaces.
Sensitivity adjuster in ultra-compact size
Despite its small size, the sensor is equipped with a sensitivity adjuster, which is very convenient when fine-tuning is required
Long-distance detection
Despite its small size, the LS series can still detect long distances, so it can also be used on wide conveyors.
High detection accuracy
Can achieve accurate detection of small objects.
Outlet method
Equipped with a two-meter bend-resistant cable.
