2-axis RTTA

2-axis RTTA

The 2-axis RTTA provides 360° rotation and 760mm linear extension within an ultra-compact footprint.  Typically <1.5mm deflection at full arm extension with 10N load, linear reproducibility of <0.2mm and rotational reproducibility of <0.2mm.

The 2-axis RTTA provides a cost-effective solution for radial distribution sample transfer applications providing arm rotation and arm extension.

Key features

  • 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

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 to provide 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.
