Rotary
Stages
Introduction
The
NSI rotary stages are specifically designed for the high accuracy
requirements of indoor antenna measurements. They are powerful,
compact and reliable. Designed to last for many years, each stage
includes the following features:
- Zero-backlash,
wear compensating worm and gear actuation
- Aligned
and doweled rotation plate
- Rotation
limited by internal switches that can be disabled in software
- Clearance
hole through spindle
- Preloaded
radial crossed roller spindle bearing is fully sealed from contamination
- Several
sets of mounting holes in rotation plate
- Includes
40' (12 m) motor cable
