Precision Pan-Tilt Unit
High-speed positioning of heavy payloads
Rugged, Compact, Feature-rich
The PTU-D300 is a family of modular computer-controlled pan-tilt units designed for fast, accurate positioning of heavy payloads. It provides high torque for payloads up to 70 lbs while maintaining speed, precision, and a small form-factor. It offers multiple mounting options and a single connection point. It is designed for demanding applications that require up to 100% duty-cycles and long-life in harsh all-weather environments.
Key features include:
- Rigid design provides steady images in windy environments
- Solid and vibration-tolerant for vehicle-mounted applications
- Large payload capacity (35 lbs. top-mount; 70 lbs. side-mount)
- Wide-range of pan speeds (<0.0064º/sec. to 100º/sec)
- Extremely precise positioning (0.0064º with microstep) allows translating object positions to global coordinates accurately
- Wide-range of pan speeds (<0.0064º/sec. to 100º/sec)
- 360º continuous-pan including pass-through for many payload types (Video, IR, Laser)
- Single connector for all video, control, power
- Flexible payload mounting (top or sides)
- Precise control of position, speed & acceleration
- Simple control from host computer via RS-232/485
- Fully sealed for outdoor/marine applications (IP67)
Applications
- Long-range surveillance
- Airborne Sensors & Communications
- Antenna positioning systems
- Satellite communications systems
- Laser ranging systems
- Automated video detection & tracking systems
- Industrial automation
- Port security
- Vehicle & shipboard surveillance systems
