PRODUCT FEATURES
High performance
Linear/Rotary motion
Adjustable parameters

Hollow rod
Soft landing
Power-oﬀ protection

Precision resolution
Long life over
100 million cycles

Provide accurate linear and rotaryactions of the Z-axis duringhigh-speed motion, with adjustablevelocity, thrust, and position
parameters, enabling complex
actions requiring high frequency
and high precision.

The product is compact, light, andthin. It employs a hollow rod design
to support pick-and-place tasks.
The intelligent soft landing function
protects the picked and placed
workpiece with precise force
control. The Z-axis has a built-in
spring to prevent the axis fromfalling oﬀ due to power-oﬀ during
vertical operations.

Regarding this product, thestroke resolution is up to 0.5 μm,
the rotary position resolution is0.005°, and the thrust repeatability is within ±3 g. Withhigh-quality guide rail-level
related components, it has aservice life of up to 100 million
cycles, and it is stable anddurable.

INSTALLATION METHOD
Install it using the screw holes on the back of the product.
Installation directions:
Horizontal direction

Vertical installation with thevertical rod pointing down

Vertical installation with thevertical rod pointing up

APPLICATION SCENARIOSThe force repeatability of ±3 g and themicron-level resolution can be applied to
the fast pick-and-place, assembly, testing,and other scenarios in semiconductors, 3C
electronics, and other industries.
The unique linear and rotary motions of theZ-axis of the VLAR series can adapt to moreabundant industrial scenarios, such aspositioning, correction, and assembly in
medical automation, 3C, and packaging
automation.
