Precision Pan-Tilt Unit
Miniature Pan-Tilt Units
Miniature Computer Controlled Pan-Tilt Unit
The PTU-D46 family of pan-tilt units provide fast, precise positioning in an extremely small and lightweight package. They are fully computercontrolled and offer programmability of speed, acceleration, power, and other parameters. The included controller handles precise kinematic motion control ccording to user set parameters.
Real-time Control with Rich Command Set
The controller includes built-in RS-232 and RS-485 interfaces and the units can be networked. They accept ASCII and binary command formats. Commands can be sent at up to 60 Hz (commands/second) for demanding applications such as laser scanning and video tracking.
Features Include:
- Fast - speeds to 300º/second
- Resolutions to 0.003º
- Load capacity over 9 lbs (4 kg)
- Precise control of position, speed & acceleration
- On-the-fl y position and speed changes
- Small form factor (< 5.2” tall)
- Light weight (head < 3 lbs)
- Single DC power input suited for battery operation
- Low cost
Applications:
- Robotic & Computer vision
- Security & surveillance
- Industrial automation
- Tracking
- Webcams
- Laser ranging
- Teleconferencing/distance learning
- Antenna pedestal
- Photography, video & special effects
