Features

- Knurled Adjustment Knob for Grip
- Small Ø1/4" (Ø6 mm) Mounting Barrel
- Durable Engraved Graduations for Easy Viewing
- Versions with 5/64" (2 mm) Hex Available
The 148-206ST(-H) and 148-202FT-H micrometers provide a travel range of 0.250" and feature engraved graduations every 0.001", while the 148-205ST(-H) and 148-201FT-H micrometers provide a travel range of 6.50 mm with 10 µm spacing between graduations. Item numbers ending in -H incorporate a 5/64" (2 mm) hex, allowing them to be actuated in space-constrained environments.
These micrometers are available with two different tip geometries. The 148-202FT-H and
148-201FT-H micrometers feature a flat tip. The spherical spindle tip, available with the
148-206ST(-H) and 148-205ST(-H) micrometers, provides a single point of contact, which minimizes positioning alignment errors. Dimensions for the 148-206ST-H and 148-202FT-H are provided in Figures 1.1 and 1.2 and complete dimensions for each micrometer can be found by clicking the Docs icon (
). Thorlabs can integrate these micrometers into many of our standard products; please contact Tech Support for details.

Many thanks! llamb

WE do not have a barrell for an 8mm hole. The 148-801ST is meant for 10mm mounting hole, while the 148-205ST is meant for 6mm mounting hole. Unfortunately, we do not have an in-between size. bogdan.voisiat
(posted 2011-09-06 12:40:30.0) Hello,
I need a micrometer that I could put into 8 mm hole.
I am interested in Micrometer Drives, 1/4" (6.5 mm). But the mounting barrel of this product is 6 mm. As I understand it can be mounted into 6 mm hole.
Is it possible to mount such micrometer into 8 mm hole?
Sincerely,
Bogdan Voisiat |
