High Accuracy
Compact Ultra-High Precision Measuring Head (Size Shift)
PULCOM mini Σ-V
Features
Compact with High Precision
This unit achieves high precision with a compact size equivalent to the previous compact head (mini Σ-II).
High Durability and High Rigidity
Our original fulcrum mechanism delivers both high durability and rigidity because of no internal sliding or friction.
Resistant to Temperature Change
The improved performance of the sensor minimizes the change in measured values that are caused by variations in the ambient temperature.
Workpiece Scratch Prevention
The improved air retract mechanism provides a soft landing on the workpiece.
