Highly accurate 0.1mm pitch thread is only one-fifth of that used for a standard-pitch head (0.5mm).
External dimensions are compatible with standard 0.5mm pitch heads.

Applications

Semiconductor-wafer positioning machinery and optical component alignment units, etc.
Precision X-Y table positioning

Precision adjustment of mirror in holder

Comparison of mounting dimensions between a fine-pitch head and a standard-pitch head at the mid-range travel position.

While the fine-pitch micrometer head has a measuring range of 6.5mm, the standard head has a larger range of 13mm.
When replacing a standard head, the fine-pitch type can use the common range in the middle of the spindle travel.
The standard and compact types of fine-pitch head are otherwise completely interchangeable.

Quick spindle feed of 1mm/rev.
