DT200-SM
Rotary Stages

Flat rotary stage (SM motor), travel n × 360°, aperture ⌀ 66 mm, repeatability ±0.008°, load capacity 11 kg, speed 41°/s

Flat precision rotary stage

The DT200-SM is a compact rotary stage with a height of only 40 mm and a rotation range of n × 360°. The stage achieves high accuracy and repeatability thanks to its thin-section bearing, precise belt/gear drive, and motor encoder feedback. With a 170 mm turntable and a 66 mm aperture, the stage is ideally suited for precise angular positioning in metrology and optical applications.

Travel range: n × 360°

Repeatability up to ±0.008°

Highly compact design with 240 × 200 × 40 mm and a 66 mm aperture

Thin-section bearing for high stiffness, low friction, and minimal build height

Options:

DC or stepper motor
Electrical or pneumatic rotary feedthrough
Precision-lapped turntable for optimal flatness and runout
Brake, rotation limiter, mechanical hard stop
Cable routing, purge air, extraction
Cleanroom variants up to ISO Class 4 (higher on request)
Beam variants: eUV, DUV, UV (X-ray and gamma on request)

Custom Extensions and Adaptations

The DT200-SM can be used as a single axis or flexibly combined into multi-axis positioning systems — particularly with linear stages of the PMT160 series or the HT160 lift stage. Adaptations include alternative motor configurations, special surface coatings, customized rotary feedthroughs, or optimized interfaces for measurement systems.

Application Fields

Metrology, optical and laser technology, test stands, laboratory analytics, research & development, experimental physics, automated scanning processes, precision positioning of sensors, optics, or samples
