2-axis Rotary Telescopic Transfer Arm
360° rotation and 760mm linear extension
The 2-axis RTTA provides a cost-effective solution for radial distribution sample transfer applications It provides 360° arm rotation and 760mm linear arm extension. What’s more, it carries out these functions with an ultra-compact footprint.
Key Specifications
- 760mm extension
- Typically <1mm deflection at full extension under 10N load
- Rotational reproducibility <0.2mm
- Linear reproducibility <0.2mm
- Clean, UHV performance
- Competitively priced compared to conventional designs
How it works
- A high torque magnetically-coupled MagiDrive precisely rotates the transfer arm to align with the desired chamber port
- A second MagiDrive is used to drive the innovative telescopic mechanism. This provides an arm extension of 760mm to transport the sample in and out of the desired satellite chamber
- The 2-axis RTTA can be motorised using stepper or SMART motors. Alternatively, the RTTA can be configured to accept any standard NEMA23 motor
