GM-12R 3 Axis Gimbal Mount

Product Videos

Newmark's high precision 3 axis motorized gimbal system is designed for general purpose pointing, scanning and tracking applications for large optics, antennae and other sensors.

Our large 3 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-12R 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 rear of the GM-12R has connectors for a clean and reliable connection.

The GM-12R is available in a low temperature (-40°C) variation.

A slip ring version is available for applications requiring 360° rotation in the azimuth and elevation axis.
