T-600 Direct-Drive Gimbal

SKU# T6001001

Price: $65,000.00

Compare

The PlaneWave T-600 gimbal is engineered to meet the needs of the most demanding applications. The T-600 is capable of carrying payloads on each side of the altitude axis for applications where multiple instruments are necessary. With rugged environments in mind, the T-600 comes standard with 2-layer non-contact sealing at each motion-surface to prevent water (light-to-moderate rain) and debris entry.

  • Load capacity of 600 lbs (272 kg)
  • Direct-drive motors on each axis for smooth, fast, and virtually silent movement of the telescope
  • Acceleration up to 70 degrees/second/second*
  • Velocity up to 150 degrees/second*
  • High resolution encoders on each axis for precise positioning
  • Zero backlash and zero periodic error
  • PointXP mount modeling software
  • Enclosed electronics with optional rubberized seals for ruggedization
  • Through the mount cabling
  • Alt/Az, Alt/Alt, or equatorial installation orientation

*T-600 performance specifications are highly conservative and currently based upon L-series gimbal performance.
