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
