QPT-20 Series Pan & Tilt Positioners

QPT-20The QPT-20 Series of Pan & Tilt positioners are designed for a wide variety of sensor positioning applications. The QPT-20 Series are rugged and durable enough for virtually any environment, including port surveillance and mobile vehicle vision systems. The QPT-20 can handle payloads up to 8 lbs/ft and provides tabletop and/or tilt axis load mounting for multiple sensor array applications. Digital Serial Integrated Control (IC) units communicate via network interface or through a dedicated controller (e.g. UniCom®). If preferred, analog units are available as effective solutions where simple command and control are required without a PC.
