T-DRV304 - Differential Micrometer Drive, 1/2" (13 mm) Travel

• Coarse Adjustment: 1/2" (13 mm) Travel, 0.5 mm per Revolution
• Coarse Resolution: 5.0 µm
• Fine Adjustment: 300 µm Travel, 50 µm per Revolution
• Fine Drive Resolution: 0.5 µm

The T-DRV304 Differential Micrometer uses a unique mechanism that converts a relatively large displacement into a relatively small displacement of the center fine adjustment spindle.

The design has the additional benefit of providing a uniform, smooth feel that is largely independent of loading. Coarse adjustment is provided via a knurled knob, while the differential adjuster features a large rubber grip which adds to the overall sensitivity of the unit.

The coarse adjustment knob gives 1/2" (13 mm) of total travel with 5.0 µm resolution, while the differential knob provides 300 µm of total travel with 0.5 µm resolution. The Ø3/8" mounting barrel is compatible with a host of standard mounting equipment.
