Aerotech has announced a new pan & tilt positioner with integrated drives and motion controls for high end camera security, surveillance and defence applications.
 The APT series has been designed to address the need for camera positioning mounts with high levels of resolution, accuracy and repeatability.
The range incorporates built in electronics, using Aerotech's Ensemble MP series motion controls and brushless servomotor drives, with top or side mount camera bracket and housing mounted connectors for camera, 24-80VDC power and Ethernet control.
A slip ring mounted in the base of the unit transfers power, motor signal and camera connections through the assembly, enabling a continuous 360º rotation of the pan-axis and a tilt axis travel range of +/-95º.
The overall specification for the standard APT-100 model is position resolution of 7.6 arc sec and accuracy to 120 arc sec. Repeatability is 30 arc sec for bi-directional positioning and 10 arc-sec for unidirectional. Maximum speed in both axes is up to 180º/sec.
The APT-100 has a 625mm diametrical footprint clearance, an overall height of approximately 352mm and a payload rating of 35kg.
The worm wheel drive mechanism includes a self adjusting gear preload feature designed to ensure consistent positioning performance over the life of the product.
The standard unit may be application customised for increased tilt stage travel, increased payload or alternative camera mounting. Additionally, Aerotech says it can provide an inertial stabilisation option, fitting gyroscopes and sensors to maintain 'line of sight' when the unit is operated on moving platforms such as aircraft, ships and land vehicles.
