GM-12 Gimbal Mount with Servo Motors
GM-12 Google Camera
Custom DirectTV Gimbal Mount
Newmark’s high precision 12″ motorized gimbal mount is designed for general purpose pointing, scanning and tracking applications for large optics, antennae and other sensors.
Our large 2 axis gimbal mounts are equipped with high performance rotary stages and offer excellent stiffness and load capacity making them suitable for a wide variety of applications.
The GM-12 gimbal mount uses high torque NEMA 23 stepper or servo motors coupled to precision preloaded worm gears providing high resolution positioning. Optical limit and home switches are standard items. The GM-12 is offered with a choice of a mirror cell for 12″ (300 mm) diameter optics or a flat payload mounting plate. The payload mounting plate is available with 1/4-20 or M6 threads. The rear of the GM-12 has connectors for a clean and reliable connection.
The GM-12 is available in vacuum compatible (10^-7 torr) and low temperature (-40°C) variations.
