GM-6 Series: Gimbal

Newmark's high precision 6" gimbal system is designed for general purpose pointing, scanning and tracking applications for small optics, antennae and other sensors.

The GM-6 gimbal system is equipped with High Performance rotary stages and offer excellent stiffness and load capacity making them suitable for a wide variety of applications.

The GM-6 comes standard with high torque NEMA 17 stepper motors. Optionally the gimbal can be equipped with rotary encoders mounted to the back of the stepper motor. For high speed applications the GM-6 is available with brushless DC servo motors.

The GM-6 is offered with a choice of a mirror cell for 6" (150 mm) diameter optics or a flat payload mounting plate. The payload mounting plate is available with 1/4-20 or M6 threads.
