Closed structure, the whole foot is dustproof and waterproof.
The Optical Linear Scale adopts a closed structure, the aluminum casing protects the grating, scanning unit and track from dust and cutting, and the elastic sealing strip protects the sealing of the casing.

The body of the reading head is waterproof and can reach a water depth of two meters. The entire foot is dustproof and waterproof up to IP54, with strong pollution resistance and good water resistance. The sensor uses a glass precision metrology grating as a measurement reference.

Strong shock resistance and good wear resistance.
The sliding seat adopts high-quality imported five bearings and a special spring structure, which can count reliably even in the case of large cutting, and has excellent repeatability.

The body of the Optical Linear Scale is made of aluminum alloy profile, which is anodized; the body of the grating ruler is thick to ensure the accuracy of the grating ruler installed on the machine tool. The ruler head is made of alloy die-casting, hard chrome plated, and corrosion-resistant.
