T-600 Direct-Drive Gimbal
Price: $65,000.00
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.
