This datasheet contains information only for selecting the appropriate model.
Be sure to read the Instruction Sheet for usage precautions prior to using the product.

SAFETY PRECAUTIONS FOR USING LASER

EQUIPMENT
The ZX0-LD uses a laser as the light source. Lasers are classified Using in the U.S.
based on EN standard (EN 60825-1). When using devices in which ZX0-LD is installed in the U.S., the
devices are subjected to the U.S. FDA (Food and Drug
WARNING Administration) laser regulations. ZX0 series is classified into Class 2
or Class 1 by the standard of IEC/EN60825-1 according to deviations
