Rugged Pan & Tilt Positioners

When your application calls for high performance and versatile platforms, the QPT-90 Series is designed for a variety of positioning and sensor support applications and is built for payloads requiring 90 foot pounds of torque. Integrated control processor (IC) units feature dual sensor serial control, lens drive and power supply interfaces making sensor integrations quick and easy. Serial IP units communicate via networked communications or dedicated joystick controller (Unicom™ controller). Analog units are effective solutions where simple command and control are required without a PC. The Sentry line takes our products to the next level by integrating stepper motors into the design for higher precision movements and broader speed control. Universal configurations provide internal and external payload interfacing. Our RF units provide one to three pass-through channels for up to 18GHz bandwidth performance.
